First Westbound Squirrel Hill Tunnel Weekend Closure July 27-30

The first of eight possible weekend closures of the westbound (inbound) Squirrel Hill Tunnel on the Parkway East (I-376) will occur July 27 to 30.

In addition to other rehabilitation work and multiple improvement activities, crews will begin removing the drop-ceiling and concrete patching the roadway inside the westbound tunnel.

When overall work is completed, vertical clearance in the westbound tunnel will increase by two feet from 13 feet, 6 inches to 15 feet, 6 inches. Preservation and rehabilitation work will also occur during the first weekend closure on the bridge that carries westbound I-376 over Commercial Street. 

The westbound closure will occur from 9 p.m. on Friday through 5 a.m. on Monday. Signs will be posted to guide motorists.

The posted detour will require westbound traffic to form a single lane exiting at the Edgewood Swissvale interchange (Exit 77). The outbound (eastbound) tunnel will remain open, although short-term traffic stoppages may occur for equipment access and material removal.      

PennDOT reminds motorists to use all open lanes to the merge point. 

To minimize impacts on businesses, different detours will be used during day and night hours. PennDOT has made improvements at key intersections and police will be posted to keep traffic moving on the posted detours.
