Pennsylvania Department of Transportation (PennDOT) announced that the Squirrel Hill Tunnel on I-376 (Parkway East) will be closed to eastbound traffic overnight. The closure begins at 10 p.m. on Monday and is expected to last until 5 a.m. on Tuesday, allowing officials to demonstrate and test a new mass‑notification system.
Detour route for outbound traffic
Motorists traveling eastbound out of Pittsburgh are instructed to follow a specific detour. The recommended path starts at the Squirrel Hill/Homestead exit (Exit 74) and continues straight onto Beechwood Boulevard toward Homestead. From there, drivers should stay on Browns Hill Road, cross the Homestead Grays Bridge, and turn left onto Route 837 (8th Avenue). Continuing on Route 837 (River Road) leads to a left turn onto the Rankin Bridge, after which traffic merges onto South Braddock Avenue and finally bears right to re‑enter eastbound I‑376 toward Monroeville.
Potential early reopening
PennDOT noted that if the testing work finishes ahead of schedule, the tunnel could reopen before the 5 a.m. deadline. Motorists are encouraged to monitor local traffic updates and the PennDOT website for any changes.
How to stay informed
Travelers can download the WTAE app for real‑time alerts or sign up for the station’s email newsletters. Both services provide breaking news and traffic information for the Pittsburgh area.
Impact on commuters
The overnight closure is expected to affect commuters who rely on the tunnel for eastbound travel during the early morning hours. By scheduling the work overnight, PennDOT aims to minimize disruption during peak commuting times. Drivers are advised to allow extra travel time and to follow the posted detour signs carefully.
About the mass‑notification system
The system being tested is designed to quickly disseminate emergency alerts to motorists in the event of a roadway incident or severe weather. Successful testing will enhance public safety by providing timely information directly to drivers’ mobile devices and in‑vehicle navigation systems.
