Speaking of federal highways built after WWII (potentially through communities), Interstate Route 80 runs through Stroudsburg and East Stroudsburg. President Johnson mentions the recent completion of this highway in his letter to Stroudsburg’s mayor celebrating the borough’s sesquicentennial:
The recent completion of the Interstate Highways through the Poconos has made Stroudsburg and the communities around it more accessible than ever before. The Federal Government is proud to have played an important role in this acheivement.Letter from President Johnson dated May 31, 1965
I do not know if any communities were demolished to build this interstate highway. It is likely that the presence of this interstate is part of the reason why some New Yorkers chose to relocate here following 9/11. It is certain that some of the local bridges owe part or all of their existence to this interstate. Many of the local bridges also owe their existence to the several creeks in the area.
The Seventh Street Bridge spans both Route 80 and McMichael’s Creek. (According to signs on this bridge it’s name is Sherrifs Forrest B. Sebring and Todd A. Martin Bridge, but the Pocono Record’s article on the renaming of this bridge highlights the controversy and public backlash to this renaming which was led by a State Representative.) Further east, the freeway and the creek are farther apart and so two separate bridges carry Broad Street over both obstacles. Heading back west, another bridge carries Main Street over Pocono Creek.
Pocono Creek and its bridge (the J. Summerfield Staples Memorial Bridge) appear to mark the western boundary of the historic core of town. On the other side of the bridge, there is an uptick in the number and frequency of auto-oriented uses and building designs.
