Notes
Took the MD 279, DE 896 detour through Newton to avoid a traffic jam and incidentally missed the Delaware Turnpike toll.

On PA 41 North, there were signs for the traffic spacing dots I had first seen on US 322 near State College. However, the road had been milled for resurfacing, so the dots were gone. There were some dots on the southbound north of the construction.

At the James River Bridge on the Blue Ridge Parkway, there is a pedestrian bridge suspended under the roadbed to allow visitors to park at the James River Visitor Center on the north side of the river to cross the river to visit a old lock and canal on the south side of the river.
