Work is set for tomorrow night that will impact traffic on Route 422 in Armstrong County.
There will be rolling closures starting at 8 p.m. Thursday through 6 a.m. Friday as crews work to remove and replace beams on the Graff Bridge, which carries Route 422 over the Allegheny River.
The closures will impact both west and eastbound traffic throughout the night.
This is a part of the $45 million bridge renovation project that will continue over the next two years.
