A section of northbound Route 28 has reopened to a single lane of traffic.
The northbound lanes were closed between the Harmar/I-76/Route 910 (Exit 11) and the Cheswick/Springdale (Exit 12) interchanges.
As a safety precaution, PennDOT closed the bridge this morning due to stone falling on the roadway from an overhead railroad bridge. The bridge has no structural issues and crews have added shoring to the structure to prevent stone from falling on the roadway.
There are no restrictions in the southbound direction.
