U.S. Route 1 north - Maryland line to Philadelphia

Reaching the end of the line in Maryland, U.S. Route 1 enters Pennsylvania in West Nottingham Township, Chester County, 50 miles southwest of Philadelphia. Photo taken 08-14-2023.

Just inches past the state line, US 1 expands from a two-lane road to a four-lane divided highway, becoming the Kennett Oxford Bypass. Photo taken 08-14-2023.

The highway intersects Sylmar Road and Nottingham Drive at an at-grade intersection. Sylmar Road leads back south into Maryland to Route 273. Photo taken 08-14-2023.

The state's first US 1 reassurance shield follows as the highway turns due north. Photo taken 08-14-2023.

Mile markers now start appearing beside the highway, and will remain there as long as access is limited. Photo taken 08-14-2023.

The highway's speed limit becomes 55 miles per hour, up from 50 just behind. Photo taken 08-14-2023.

US 1 now approaches Ridge Road, the highway's last at-grade intersection for more than 20 miles. Photo taken 08-14-2023.

From here, Ridge Road goes west along the south side of the Nottingham County Park to Fremont Road, and east a short distance to Stoney Lane, alternately known in Maryland as Wilson Road. Photo taken 08-14-2023.

US 1 now earnestly becomes a freeway, and the first exit, intersecting Pennsylvania Route 272 and serving the community of Nottingham, is a mile away. Photo taken 08-14-2023.

There is a Wawa gas station at this exit, and the facilities of Herr's potato chips are also here. Photo taken 08-14-2023.

Before the exit, US 1 passes under Park Road, which runs along the north end of the county park. Photo taken 08-14-2023.
