It started on Tuesday at 7 a.m. with a right lane closure heading toward Rochester. PennDOT said that will last just one week, but not long after that in mid to late June, the entire bridge will shut down for 67 days. It’s part of a nearly $6.7 million project to rehab and preserve the structure.

The detour will take drivers down to the Monaca East Rochester bridge. That detour brings concerns about the heavy traffic now traveling through downtown Monaca.

The bridge will still be open for pedestrians and bicyclists during the full closure. The hope is for the entire project to be wrapped up by the end of the year.
