The underpass at Township Line Road, where the Turnpike mainline bridge is under construction, will be closed at 6 p.m. between Union Meeting Road and Arch Street in Plymouth and Whitpain Townships until 6 a.m., Sept. 21. Posted detour routes will direct traffic over Arch Street, Jolly Road and Union Meeting Road.
Message boards have been activated to alert motorists of the scheduled closure.
