An alternative detour will be in place during this weekend’s closure of the eastbound (outbound) Squirrel Hill Tunnel for ongoing construction work.

During the closure, a detour on the Parkway East (Interstate 376) will be in effect from 10 p.m. on Friday through 6 a.m. on Monday. Expect significant delays and allow extra time.

The ramp from Edgewood/Swissvale (Exit 77) to eastbound I-376 will also be closed this weekend, so PennDOT will use the alternative tunnel detour that sends traffic through Wilkinsburg. Signs will be posted to guide drivers.
