Replacement of traffic signals will cause lane closures at several McKnight Road intersections starting tonight, PennDOT announced.

The closures will occur as needed starting at 8 p.m. Mondays through Thursdays through Sept. 23 between Medical Center Drive and Pine Creek Road in Ross and McCandless. The work will wrap up by 6 a.m. daily.

The project includes replacing vehicular and pedestrian signals, controllers, poles, signing and pavement markings.
