Reminder: First Westbound Squirrel Hill Tunnel Closure this Weekend

The detours will be coming through Regent Square.

The first of eight possible weekend closures of the westbound (inbound) Squirrel Hill Tunnel on the Parkway East will occur this weekend, beginning Friday night. 

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

The outbound (eastbound) tunnel will remain open, although short-term traffic stoppages may occur for equipment access and material removal.  

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. 

PennDOT has created a website to provide the public access to travel times on the detour routes. The website is available at:

http://public.jamlogic.com/Trafax/264/1

Motorists are advised to visit the website before traveling and plan trips accordingly. Traffic cameras will be added to the site soon.      

To minimize impacts on businesses, which will remain open, 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.

PennDOT is also reminding motorists the westbound Squirrel Hill Tunnel is tentatively scheduled to close next weekend, Aug. 3-6.

The $49.5 million project to rehabilitate the Squirrel Hill Tunnel includes updating electrical, lighting, air control and ventilation systems, structural repairs to the walls and arched ceiling, tile repairs, installation of a water line and other improvements. To minimize impacts on the traveling public, rehabilitation work on the bridge that carries the Parkway East over Commercial Street will be performed as part of the tunnel project. Expansion dam on ramps at the Edgewood Swissvale interchange (Exit 77) will also be replaced.

PennDOT advises motorists to use caution, slow down, and expect changing traffic patterns when traveling through the area. Visit 511pa.com or call 511 from any phone to check traffic conditions on major roadways before traveling.
