Baltimore-Washington Parkway north - US 50 to Maryland Route 175
The Baltimore-Washington Parkway, under National Park Service maintenance, heads away from its interchange with the Capital Beltway (Interstate 95/495) under Maryland Route 193 (Greenbelt Road), in the Greenbelt area of Prince George's County. Photo taken 04-09-2025.
The subsequent exit serves NASA's Goddard Space Center and a branch of the U.S. Park Police via MD 193. Photo taken 04-09-2025.
Just past the onramp from MD 193 sits Parkway mile marker 7. Photo taken 04-01-2025.
This is followed by the Spellman Overpass linking Greenbelt's Ridge Road with Hanover Parkway beside Eleanor Roosevelt High School. Photo taken 04-01-2025.
A little further along, Goddard has its own exit off the Parkway for employees. Photo taken 04-01-2025.
The Goddard exit was closed at this time. Photo taken 04-01-2025.
This overpass under construction takes southbound traffic into Goddard. Photo taken 04-01-2025.
Just after receiving the northbound onramp from Goddard, the Parkway reaches mile marker 8. Photo taken 04-01-2025.
The highway shows off a tree-scattered median and brick guardrail, a typical fixture of this segment. Photo taken 04-01-2025.
The speed limit is 55, supposedly radar-enforced. Photo taken 04-01-2025.
A brown guardrail appears in the median as the highway crosses Beck Branch. Photo taken 04-01-2025.
Powder Mill Road, which leads west toward Beltsville, is intersected in half a mile. Photo taken 04-01-2025.
This exit serves the National Wildlife Visitor Center on the Patuxent Wildlife Refuge. Photo taken 04-01-2025.
The Powder Mill exit sits ahead. Photo taken 04-01-2025.
This is a spot particularly prone to traffic congestion. Photo taken 04-01-2025.
The Parkway crosses Powder Mill and then receives an onramp from it. Photo taken 04-01-2025.
The Parkway then comes upon an interchange with Maryland Route 197, which heads west to Laurel and southeast to Bowie. Photo taken 04-01-2025.
Bowie is a right turn away at the interchange along with the Bowie Health Center. Photo taken 04-01-2025.
This exit leads to the Montpelier Mansion and Arts Center in South Laurel. Photo taken 04-01-2025.
There are two lanes each for Parkway through traffic and MD 197. Photo taken 04-01-2025.
The MD 197 ramp gore. Photo taken 04-01-2025.
The Parkway has two bridges over each carriageway of MD 197. Photo taken 04-01-2025.
After MD 197, the Parkway crosses the Patuxent River into Anne Arundel County. Photo taken 04-01-2025.
The Patuxent bridge itself is seen here. Photo taken 04-01-2025.
The next 10 miles of the highway are a deer crossing area. Photo taken 04-01-2025.
At mile marker 14, trees again fill the Parkway's median. Photo taken 04-01-2025.
The next exit is at Maryland Route 198, and the ramp to MD 198 east toward Fort Meade lies ahead. Photo taken 04-01-2025.
The ramp to MD 198 east parts with the northbound Parkway, which then receives traffic from that direction of MD 198. Photo taken 04-01-2025.
There is a rather interesting design choice (certainly unintentional) for the sign pointing the way to MD 198 west toward Laurel. Photo taken 04-01-2025.
A closer look at MD 198's overpass over the Parkway. Photo taken 04-01-2025.
There is a rather tight cloverleaf ramp to westbound MD 198. Immediately to the west of here sits the Russett Green development on the east side of Laurel. Photo taken 04-01-2025.
An interchange with Maryland Route 32 (Patuxent Freeway) then approaches. A ramp to MD 32 east toward Fort Meade is half a mile away. Photo taken 04-01-2025.
The Parkway takes time prior to MD 32 to cross the Little Patuxent River. Photo taken 04-01-2025.
Half a mile past the ramp to MD 32 east, a cloverleaf ramp leads to MD 32 west toward the Columbia area of Howard County. Photo taken 04-01-2025.
This offramp contains access to the National Cryptologic Museum. Photo taken 04-01-2025.
Westbound MD 32 leads to the Savage station of MARC's Camden Line via Dorsey Run Road. Photo taken 04-01-2025.
From here, MD 32 goes through Savage, then passes along the south side of Columbia, directly serving the villages of Owen Brown, Hickory Ridge and River Hill. Photo taken 04-01-2025.
After MD 32, the Parkway passes under Canine Road, one of the main roads in the Fort Meade/Annapolis Junction area. Photo taken 04-01-2025.
Canine Road has a partial two-ramp interchange with the Parkway, and its onramp to the northbound carriageway is at right. Photo taken 04-01-2025.
Jessup and (again) Fort Meade are served by the next interchange. Photo taken 04-01-2025.
The interchange intersects Maryland Route 175 (Jessup Road west/Annapolis Road east) toward the central part of Columbia and Odenton in half a mile. This is the final northbound interchange along the National Park segment of the Parkway. Photo taken 04-01-2025.
A southbound-facing sign marking the north end of the National Park segment is at left. Photo taken 04-01-2025.
The ramp to MD 175 is ahead, and Maryland's State Highway Administration will soon take control of the Parkway. Photo taken 04-01-2025.
