Saw Mill Run Boulevard closure could delay some Pittsburgh Public School bus routes

PITTSBURGH — Delays on a bridge project could impact the first day of school for some Pittsburgh Public School students.

The closure on Saw Mill Run Boulevard (Route 51) between Crane Avenue and Woodruff Street was supposed to end by Monday morning. But, PennDOT announced that the around-the-clock closure will continue through Thursday afternoon, weather permitting, as work to demolish a bridge continues.

Pittsburgh Public Schools warns there could be “significant delays” for bus routes on the road until the closure is over.

Officials say the extension is the result of “unforeseen field conditions and utility relocation work.”

Until the demolition project is complete, traffic will be detoured along the following routes:
