U.S. Route 1 north - Baltimore to Pennsylvania line


U.S. Route 1 goes northeast as Belair Road from its intersection with North Avenue and Gay and Port streets in east Baltimore, Maryland. At that intersection is where US 1 turns from North Avenue onto Belair Road. Photo taken 06-15-2024.


The route meets Sinclair Lane at a traffic signal before passing under the Baltimore Terminal Subdivision. Photo taken 06-15-2024.


A 30 MPH speed limit and US 1 shield are affixed to a light pole just past Ravenwood Avenue. Photo taken 06-15-2024.


Seen at left is Clifton Park, while rowhomes line the right side of the street. Photo taken 06-15-2024.


Past Elmley Avenue, the route eases downhill. Photo taken 06-15-2024.


US 1 now encounters Erdman Avenue. At left, it runs along the northeast side of Clifton Park to Harford Road. At right, it becomes Maryland Route 151 and makes its way through Dundalk and Edgemere in southeast Baltimore County, coming to an end at Sparrows Point. There is also a truck route of U.S. Route 40 that turns right from Belair Road onto Erdman here. Photo taken 06-15-2024.


The next signal is at Lake Avenue. Photo taken 06-15-2024.


While going downhill toward Herring Run Park, US 1 meets Chesterfield Avenue. Photo taken 06-15-2024.


The route reaches the bottom of the hill and crosses a pedestrian trail and Herring Run, a tributary of the Back River. Photo taken 06-15-2024.


US 1 then climbs back uphill, cresting at Seidel Avenue. Photo taken 06-15-2024.


Now in the Frankford neighborhood, US 1 intersects Moravia Road. At left, it leads to Harford Road where it becomes Cold Spring Lane. At right, Moravia runs southeast to interstates 895 and 95 and also has access to US 40. Photo taken 06-15-2024.


Another 30 MPH sign is posted at Southern Avenue. Photo taken 06-15-2024.


The route then intersects Woodlea Avenue at the renowned Woodlea Bakery. Photo taken 06-15-2024.


Frankford Avenue, intersected here, is the main drag through Frankford. Photo taken 06-15-2024.


At Berger Avenue there is another hillcrest. Photo taken 06-15-2024.


US 1 then meets another northeast Baltimore arterial, Hamilton Avenue. Photo taken 06-15-2024.


A US 1 shield without directional banner (something BCDOT is notorious for) is situated after Hamilton. Photo taken 06-15-2024.


Making its way into the Cedmont neighborhood, the route intersects Parkmont Avenue. Photo taken 06-15-2024.


The next signal is at Kenwood Avenue, which goes east into Baltimore County, to the Linhigh area of Overlea. Photo taken 06-15-2024.


Fleetwood Avenue is US 1's final signal in Baltimore city. Photo taken 06-15-2024.


At Maple Avenue (right) and Northern Parkway (left), US 1 leaves the city and enters Baltimore County. Northern Parkway is a well-known local arterial running east-west across the width of the city; its west end is at Liberty Heights Avenue in northwest Baltimore. Photo taken 06-15-2024.


Entering Overlea, the route intersects the namesake Overlea Avenue. Photo taken 06-15-2024.


After the Willow Avenue intersection, the route goes steeply downhill. Photo taken 06-15-2024.


The next two signals are respectively at Taylor and Fullerton avenues. Taylor Avenue acts as a link between Overlea and the south side of Towson, via Parkville. Photo taken 06-15-2024.


The Taylor Avenue light is seen here. Photo taken 06-15-2024.


This is followed by US 1 reassurance. Now out of Baltimore city limits, the State Highway Administration is responsible for maintaining US 1 at this point. Photo taken 06-15-2024.


Thorncliff Lane, at right, leads to a section of Linhigh Avenue. Photo taken 06-15-2024.


US 1 intersects Fowler Avenue as it approaches its interchange with Interstate 695. Photo taken 06-15-2024.


The final intersection prior to I-695 is Overton Avenue. Photo taken 06-15-2024.


I-695 (Baltimore Beltway) has control cities of Towson and Essex at this interchange. In the absence of a Patapsco River crossing, it has termini at Sparrows Point, clockwise from here, and Hawkins Point counterclockwise. Photo taken 06-15-2024.


US 1 crosses over the Beltway here. Photo taken 06-15-2024.


The cloverleaf ramp to the outer loop toward Towson then branches off. Photo taken 06-15-2024.


The first intersection after I-695 is Lincoln Avenue. Photo taken 06-15-2024.


Traffic from the outer loop of 695 comes in at right along with US 1 reassurance. Photo taken 06-15-2024.


Now in Fullerton, US 1 approaches Rossville Boulevard. There is a notation indicating its access to Franklin Square Hospital. Photo taken 06-15-2024.


Going uphill, the route then nears Putty Hill Avenue (left) and Ridge Road (right). Photo taken 06-15-2024.


Intersected here is a disjoint section of Putty Hill that stops at Walther Boulevard just to the west. It then picks up where Rossville Boulevard leaves off and runs through Parkville and Towson. Photo taken 06-15-2024.


The route then goes downhill at 40 miles per hour. Photo taken 06-15-2024.


Then, it crosses over Maryland Route 43 (White Marsh Boulevard) before meeting Wholesale Club Drive at a traffi signal. Photo taken 06-15-2024.


A ramp to westbound MD 43 leading to the outer loop of I-695 sits ahead. Photo taken 06-15-2024.


Opposite the MD 43 ramp, US 1 intersects Dunfield Road, a connector to Walther Boulevard. Photo taken 06-15-2024.


After that, the highway intersects Klosterman Avenue. Photo taken 06-15-2024.


US 1 goes downhill again and nears Olde Forge Lane. Photo taken 06-15-2024.


Approaching Necker Avenue, US 1 enters Perry Hall. Photo taken 06-15-2024.


As it starts to go back uphill, the route has a signal at Slater Avenue. Photo taken 06-15-2024.


Silver Spring Road is intersected at the subsequent signal. Photo taken 06-15-2024.


Beginning just to the northwest at Joppa Road, Silver Spring Road is a residential arterial that has access to the White Marsh Mall via Perry Hall and Honeygo boulevards. It dead-ends just west of I-95, then resumes east of the Interstate and runs to Maryland Route 7 (Philadelphia Road). Photo taken 06-15-2024.

A US 1 shield is placed immediately past Silver Spring Road. Photo taken 01-14-2022.

US 1 runs mostly straight as it continues to work its way through Perry Hall, with several changes in elevation and commercial development galore. Photo taken 01-14-2022.

After intersecting several side streets, the route encounters the Perry Hall Centre which has its own traffic light at its main entrance. Photo taken 01-14-2022.

Belair Road then encounters the end of the western leg of Joppa Road, which heads toward county seat Towson via Parkville, and a disjoint segment of Ebenezer Road, whose name reappears to the southeast in Middle River off U.S. Route 40. Photo taken 01-14-2022.

Just north of that sits a light at India Avenue, a residential street, and the beginning of East Joppa Road, which one can take to Maryland Route 7 outside of White Marsh. Photo taken 01-14-2022.

US 1 now passes through a highly residential section of Perry Hall. Due to the lack of shoulders, mailboxes here are positioned sideways on the sidewalk, just like on Silver Spring Road nearby. Photo taken 01-14-2022.

The speed limit is 40 miles per hour as a signal for Perry Hall's fire station sits ahead. Photo taken 01-14-2022.

A "new" traffic light (SHA has a history of forgetting to take these signs down) sits at a retail area in the distance. Photo taken 01-14-2022.

The light sits at Klausmier Road, and sits just past the garage of the Klausmeier family, one of whose members, Johnny, has been a crew chief for a NASCAR team co-owned by Tony Stewart. Photo taken 01-14-2022.

The route's center left-turn lane lingers, and it now approaches a light at Baker Lane and Chapel Road. Photo taken 01-14-2022.

Baker Lane leads toward Gunpowder Elementary School, while Chapel Road goes back in the direction of East Joppa Road, which intersects Honeygo Boulevard just east of that. Photo taken 01-14-2022.

US 1 reassurance sits just past that signal, at a separate light serving the Perry Hall North retail strip. Photo taken 01-14-2022.

The route subsequently intersects a now-disconnected stub of Forge Road, which was severed by Honeygo's construction. Photo taken 01-14-2022.

The north end of Honeygo Boulevard is US 1's final traffic light in the Perry Hall hub. Honeygo's extension from Ebenezer Road outside of White Marsh was completed in 2010. Photo taken 01-14-2022.

As it curves and descends into a heavily forested area, US 1 intersects Perry Hall Road, which was extended in 2016 to facilitate construction of the Gunpowder Overlook subdivision. Photo taken 01-14-2022.

The median temporarily disappears as the route approaches Miller Road. Photo taken 01-14-2022.

US 1 now becomes a divided highway as a rock formation sits next to the right side of the highway. Photo taken 01-14-2022.

It then approaches a crossing of Gunpowder Falls and a Gunpowder Falls State Park trailhead. Photo taken 01-14-2022.

The road now prepares to consolidate back into a two-way trafficway. Photo taken 01-14-2022.

A traffic light with Mount Vista Road sits just ahead, after a slight curve and uphill climb. Photo taken 01-14-2022.

K.P. Huber's produce stand on the north side of the signal gives this intersection a rural touch. Photo taken 01-14-2022.

The route continues north, still at 50 miles per hour. Photo taken 01-14-2022.

As it approaches Kingsville, the speed drops to 40 miles per hour. Photo taken 01-14-2022.

The highway intersects Cheryl Avenue as it enters the Kingsville hub. Photo taken 01-14-2022.

The speed limit drops as the route goes slightly uphill. Photo taken 01-14-2022.

The route passes by a car dealership in between intersections with Longfield Drive and Goettner Road. Photo taken 01-14-2022.

As it heads into Kingsville's center, US 1 passes by the Kingsville Plaza shopping center. It then comes up on intersections with Jerusalem Road as well as Sunshine Avenue to the left and Bradshaw Road to the right.  Photo taken 01-14-2022.

At the light ahead, Jerusalem Road heads toward the historic Jerusalem Mill and a Gunpowder Falls trailhead, indirectly to the Jericho covered bridge, and out to Maryland Route 152 in Harford County. Sunshine Avenue becomes Fork Road at Maryland Route 147; Fork Road in turn becomes Baldwin Mill Road, which assumes State Highway Administration maintenance as Maryland Route 165 just north of Baldwin. Bradshaw Road meanwhile passes through the hamlet of Upper Falls, crosses Interstate 95 and dead-ends past Maryland Route 7. From US 1 north, Sunshine is only accessible through a right turn onto Jerusalem and then left on Bradshaw back to the US 1 light. Photo taken 01-14-2022.

Kingsville light behind it, US 1 forges northeast toward its next big hub, Bel Air. Photo taken 01-14-2022.

After a short uphill, the route descends slightly. Photo taken 01-14-2022.

As it passes the Kings Court Motel, the speed limit remains 40 for the time being. Photo taken 01-14-2022.

The speed has now increased back to 50, with houses lining either side of the highway. Photo taken 01-14-2022.

An intersection with New Cut Road approaches; its position along the highway is tricky enough for it to be announced by this overhead mast-mounted sign with flashers. Photo taken 01-14-2022.

Past New Cut Road, US 1 proceeds sharply downhill into trees, marking another portion of Gunpowder Falls State Park. Photo taken 01-14-2022.

The route has a slight S-curve near the bottom of the hill. Photo taken 01-14-2022.

At the bottom of the hill, the highway comes across the head of the Little Gunpowder trail. Photo taken 01-14-2022.

US 1 now prepares to cross the Little Gunpowder Falls into Harford County. Photo taken 01-14-2022.

A moderate uphill curve follows the bridge; slower traffic is directed to remain in the right lane. Photo taken 01-14-2022.

Harford County's first US 1 reassurance. Photo taken 01-14-2022.

A crossroads with Reckord Road approaches, at which the safe speed is 40. Photo taken 01-14-2022.

The Reckord intersection is augmented by a set of flashers, which was erected around 2006. Photo taken 01-14-2022.

The route then intersects Wilgis Road, leading into the community of Pleasant Hills, at the site of Log Cabin Candies' facility. Photo taken 01-14-2022.

US 1 goes uphill as it approaches its intersection with Maryland Route 152. Photo taken 01-14-2022.

Monkton's Ladew Gardens are a drive several miles leftward; meanwhile Jerusalem Mill and its accompanying historic village can again be reached by backtracking onto MD 152 south. A center cable barrier is present here. Photo taken 01-14-2022.

MD 152 goes north through the sprawling residential area of Fallston to MD 146 south of Madonna, which is west of Jarrettsville. MD 152 also goes south to I-95, intersecting US 40 outside of Joppatowne, and to the western entrance of Aberdeen Proving Ground's Edgewood Arsenal. Photo taken 01-14-2022.

US 1 reassurance follows the MD 152 light it is now in a busy commercial area that represents the south side of Fallston. Photo taken 01-14-2022.

The route has a flashing intersection with Milton Avenue, which used to serve the Fallston General Hospital. It was replaced with Bel Air's Upper Chesapeake Medical Center in 2000, and the "Hospital" arrow on the flashers now points straight to reflect this. Photo taken 01-14-2022.

The next light, Fallston Boulevard, serves a Walmart and a residential community. Several car dealerships also line this section of the highway. Photo taken 01-14-2022.

After going downhill and a curve to the left, US 1 intersects Connolly Road to the left, leading to the Benson post office, and Whitaker Mill Road right. Whitaker Mill has a truss crossing over Winters Run and becomes Ring Factory Road, serving subdivisions on the south side of Bel Air. Photo taken 01-14-2022.

US 1 now approaches a signal intersecting the north end of Maryland Route 147 (Harford Road) and the south end of U.S. Route 1 Business, which assumes the Belair Road name at the intersection. Photo taken 01-14-2022.

The markers for each intersecting route sit here. Photo taken 01-14-2022.

The route has reached the intersection in question. MD 147 heads south back toward and into the city of Baltimore. US 1 Business, shown here with a green-on-white marker, used to be mainline US 1's path into downtown Bel Air until the mid-1960s, when the Bel Air Bypass opened. Photo taken 01-14-2022.

The names of each intersecting road are displayed on the signal mast. US 1 now becomes the Bel Air Bypass, passing to the west of the center of Bel Air, the seat of Harford County. Photo taken 01-14-2022.

US 1 reassurance flanks the route as it expands into a four-lane divided highway, initially with a concrete median, which shortly turns into a grassy one. Photo taken 01-14-2022.

Rising Sun in the northern part of neighboring Cecil County is 27 miles from this sign. Downtown Philadelphia, Pennsylvania is an 81-mile drive away, the entire distance from this point covered by US 1. Photo taken 01-14-2022.

The speed limit is now 50 miles per hour. Photo taken 01-14-2022.

The excess asphalt in the median here is a ramp stub from when US 1 was planned to be a full freeway the entire way between Baltimore and Philadelphia. The ramp was planned to be part of a partial interchange between the freeway and Belair Road, which mainline US 1 would have run separate from had the freeway been built in its entirety. Portions of this freeway that did end up being built, in addition to the Bel Air Bypass, include part of the Perring Parkway (Maryland Route 41) in northeast Baltimore and Parkville, as well as US 1's Kennett Oxford Bypass in Chester County, Pennsylvania. Photo taken 01-14-2022.

The Bel Air Bypass is one of Maryland's designated headlight use corridors; this was once of the safety enhancement efforts put in place in the wake of a November 2008 fatal accident on the bypass about two miles north of this. Photo taken 01-14-2022.

The right lane ends ahead as US 1 prepares to converge back into a two-lane undivided trafficway. Photo taken 01-14-2022.

As the right lane ends, a sign announces a forthcoming exit ramp from the bypass to southbound Maryland Route 24, leading a few miles southward to Interstate 95 and the Edgewood area. Photo taken 01-14-2022.

While the southbound lane remains a straight shot here, the northbound carriageway curves considerably to the left as the divided highway ends. Photo taken 01-14-2022.

Now a single carriageway, US 1 crosses over Winters Run, which as Otter Point Creek further south, is a tributary of the Bush River. Photo taken 01-14-2022.

The southbound MD 24 exit is a quarter of a mile away. Photo taken 01-14-2022.

Before the exit, US 1 climbs up a steep hill, and this brown sign - one of many across Maryland directing travelers to various points of interest across the state - notifies that Rocks State Park in northern Harford County as well as Bel Air's historic landmarks can be accessed via the next interchange, just further to the north. Maryland Route 924, explained a few photos down, is marked for the first time on the bypass here. Photo taken 01-14-2022.

After crossing over Tollgate Road, a second northbound lane opens up for the MD 24 exit ramp. This ramp is part of an uncoventional interchange that opened in 1987 along with the current MD 24 corridor from here to I-95; it includes a traffic signal between ramps covered below. The Upper Chesapeake hospital is noted toward the bottom of the gantry pole, and by now, mile markers reflecting US 1's distance from the Baltimore County line have begun to line the highway; mile marker 4 sits just beyond the gantry. Photo taken 01-14-2022.

The ramp to MD 24 south leaves US 1, and the second northbound lane lingers until just past the forthcoming traffic signal. Photo taken 01-14-2022.

US 1 splits back into a divided highway with concrete median as the southbound carriageway's second lane disappears. Photo taken 01-14-2022.

Ahead of the signal, a sign notes that the right lane disappears past the signal. Photo taken 01-14-2022.

The traffic signal is where MD 24 south splits from US 1 south and connects with the above-mentioned ramp from US 1 north into Bel Air's retail district. It is a so-called seagull intersection where traffic continuing on US 1 south rather than turning onto MD 24 south does not have to stop at the light, whereas northbound US 1 traffic does have to deal with the light. The movements from US 1 south to MD 24 south and from MD 24 north to US 1 south cross over each other, and are thus not permitted simultaneously. This intersection is not intended to facilitate movements from MD 24 north to US 1 north, as those are provided by a long exit ramp to the north of here. Photo taken 01-14-2022.

Past the signal, drivers are once again reminded to merge left if they are still in the right lane. This signage has gone through multiple iterations over the years in order to keep up with SHA's design guidelines and people's driving patterns. Photo taken 01-14-2022.

The concrete median now becomes a guardrail; this was added in 2012 in response to the aforementioned 2008 accident. Photo taken 01-14-2022.

A forthcoming five-ramp interchange serves Maryland Route 924 south into downtown Bel Air and Maryland Route 24 north toward Forest Hill. Photo taken 01-14-2022.

This stretch of US 1 remains a mandatory headlight use area. While the bypass contains two southbound lanes here in anticipation of the MD 24 signal, US 1 north remains a single lane for now. Photo taken 01-14-2022.

The cross road at the interchange ahead, for both routes, is Rock Spring Road. This sign further explains that it becomes Rocks Road via MD 24 north and Bel Air's Main Street via MD 924 south (in fact, it becomes Rock Spring Avenue beforehand, roughly at Bel Air's corporate limits, a distance north of downtown). Photo taken 01-14-2022.

The long ramp which takes northbound MD 24 traffic onto the bypass becomes visible after US 1 emerges from the woods. The ramp has its own sign informing drivers to turn on their headlights regardless of light or weather condition. Photo taken 01-14-2022.

These signs warn of the impending ramp merge. Photo taken 01-14-2022.

The ramp now becomes a second northbound lane for the bypass, and MD 24 is now fully concurrent with US 1. An advance sign for the exit for MD 924 south sits here, with the Vale Road overpass in the distance. Photo taken 01-14-2022.

A dual US 1/MD 24 route shield sits just past the overpass. Photo taken 01-14-2022.

This brown sign, which the State Highway Administration uses to promote points of interest across Maryland, states that Rocks State Park is an eight-mile drive north on MD 24. Included at the bottom is a pictorial notation for the Fiore winery on Harford County's northern fringes. Photo taken 01-14-2022.

A mounted overhead sign states the MD 924 ramp sits just ahead. MD 924 was MD 24's original alignment through downtown Bel Air before its current divided highway alignment bypassed it in 1987. Photo taken 01-14-2022.

An exit sign and mile marker in the ramp's gore. The onramp from MD 24 south to US 1 south lies just behind. Photo taken 01-14-2022.

The right northbound lane then prepares to become the cloverleaf ramp on which MD 24 north leaves the bypass. That ramp was added in 1983; beforehand, both directions of Rock Spring Road/Avenue were accessed from the previous ramp. Photo taken 01-14-2022.

US 1's 5.8 mile marker for Harford County precedes the exit. Photo taken 01-14-2022.

After US 1 crosses over Rock Spring Road, on a bridge which was paved over with asphalt in 2021 after decades of being concrete-surfaced, MD 24 departs the bypass. This gantry directs drivers staying on US 1 north to keep left. Meanwhile, MD 24 from here goes north through the Forest Hill area and to Rocks State Park. This sign may be referencing the actual hamlet of Rocks on the north side of the park and Deer Creek. Photo taken 01-14-2022.

Just past the MD 24 ramp gore. The northbound ramp to Rock Spring Road is situated just ahead. Photo taken 01-14-2022.

As it passes under a northbound-facing gantry, US 1 is now two lanes, but not for long. Photo taken 01-14-2022.

The onramp from Rock Spring Road to US 1 north now prepares to merge in. Photo taken 01-14-2022.

An intersection with Water Tower Way, which leads north to Maryland Route 23, is a quarter of a mile away. Water Tower Way used to be part of MD 23 itself. That will be explained in greater detail below. Photo taken 01-14-2022.

A MD 23 shield precedes the intersection. When the Bel Air Bypass was first built in the mid-1960s, MD 23, itself on a new alignment, East-West Highway, curved slightly to the south, then east on Granary Road to Conowingo Road, and what is now Water Tower Way was a ramp to US 1. The Hickory Bypass project in 2000 realigned and extended MD 23 eastward to the new bypass. Photo taken 01-14-2022.

US 1's carriageways split and narrow as a left-turn lane for Water Tower Way appears in the median. A ramp from southbound Water Tower Way to southbound US 1 sits behind this photo It was around this point where, prior to 2000, the Bel Air Bypass curved rightward and ended at a traffic signal at Conowingo Road. Photo taken 01-14-2022.

Now changing names to the Hickory Bypass, mainline US 1 prepares to intersect US 1 Business. Before the extension of the bypass, mainline US 1 turned from just south of this point onto Conowingo Road and passed directly through Hickory, and US 1 Business reached its northern terminus at that point. Photo taken 01-14-2022.

US 1 goes straight ahead to Rising Sun, turning left takes you toward Hickory, and turning right back toward downtown Bel Air. Photo taken 01-14-2022.

A green-on-white marker directs drivers to northbound US 1 Business. Photo taken 01-14-2022.

US 1 continues northeastward, now with concrete median; the speed limit is still 50. Photo taken 01-14-2022.

The highway now approaches a junction with Maryland Route 23, which heads west toward Jarrettsville. Photo taken 01-14-2022.

MD 23, known here as East-West Highway, has its eastern terminus here. Just under seven miles long, East-West Highway was built around the same time as the Bel Air Bypass, replacing old MD 23, Jarrettsville Road, to the north. Its current alignment in turn came about with the construction of the Hickory Bypass. Photo taken 01-14-2022.

US 1 then proceeds downhill through woods; the median is once again grassy with a guardrail. Photo taken 01-14-2022.

The highway now approaches a junction with Maryland Route 543, known here as Fountain Green Road. Photo taken 01-14-2022.

MD 543 leads north from here toward Ady, a hamlet in northern Harford County, and south along the eastern edge of the Bel Air area to the namesake Fountain Green, and to Interstate 95 and then U.S. Route 40 in Belcamp-Riverside. Photo taken 01-14-2022.

The MD 543 traffic signal sits in the distance, at the top of a preceding hill. Photo taken 01-14-2022.

There is a US 1 reassurance shield following the MD 543 intersection. Photo taken 08-14-2023.

The right lane ends just ahead, as the Hickory Bypass will shortly end and US 1 will reduce to one lane in each direction. Photo taken 08-14-2023.

The speed limit remains 50 as US 1 consolidates into a single carriageway while curving to the left. Photo taken 08-14-2023.

The route now comes up on the north end of US 1 Business. Photo taken 08-14-2023.

The final bypass mile marker sits just prior to the US 1 Business intersection. Photo taken 08-14-2023.

Taking the Conowingo Road name with it, US 1 proceeds northward away from the Bel Air hub. Photo taken 08-14-2023.

The route nears an intersection with Ruffs Mill Road, which leads southeast to Thomas Run Road. Photo taken 08-14-2023.

It then intersects Waverly Drive, a residential street. Photo taken 08-14-2023.

A scattering of trees and buildings surround the approach to the next intersection, Gibson Road. Photo taken 08-14-2023.

Gibson Road, at left, leads west back to MD 543, with a number of sharp curves leading there. Photo taken 08-14-2023.

After that, US 1 intersects Robertson Road, the main street in Gibson Manor, an older subdivision in the area. Photo taken 08-14-2023.

Passing more farmland, US 1 then reaches White House Road, unrelated to the landmark of Washington, DC. Photo taken 08-14-2023.

More trees and corn surround the highway as it prepares to go down a fairly steep hill. Photo taken 08-14-2023.

Before said hill, US 1 meets at a forked intersection Forge Hill Road, which represents its former, curvier alignment through the Deer Creek valley ahead. Photo taken 08-14-2023.

After a gradual leftward curve, US 1 enters a swath of trees at the top of the hill and prepares to intersects Kalmia Road at a crossroads. Photo taken 08-14-2023.

Kalmia Road goes west from here to Sandy Hook Road, where it becomes Walters Mill Road and begins paralleling Deer Creek; it also goes east to intersections with Forge Hill and White House roads, and out to Thomas Run Road. Photo taken 08-14-2023.

The highway goes back uphill past Kalmia Road, with another cornfield wedged in among the trees at left. Photo taken 08-14-2023.

The route next intersects Allibone Road, a connector between Kalmia and Forge Hill. Photo taken 08-14-2023.

US 1 goes downhill again, with a gradual righthand curve, as it approaches Deer Creek. Photo taken 08-14-2023.

The highway reaches the bottom of the hill and crosses the creek - a tributary of the Susquehanna River and important waterway for Harford County, passing through the Susquehanna and Rocks state parks and numerous stretches of farmland. It is additionally the source of many smaller streams across the county. Photo taken 08-14-2023.

Climbing back uphill, US 1 reaches a sharper curve to the right. Photo taken 08-14-2023.

The route's next intersection is with Sandy Hook and Trappe roads, the latter leading to Maryland Route 136. Photo taken 08-14-2023.
