Southbound Route 28 Opened to Two Lanes at the Highland Park Bridge Interchange Today in Allegheny County


Pittsburgh, PA – PennDOT District 11 is announcing southbound Route 28 has opened to two lanes of unobstructed traffic at the Highland Park Bridge interchange in Sharpsburg and Aspinwall boroughs, Allegheny County today, Wednesday afternoon, December 20.

A newly constructed southbound lane has opened on mainline Route 28 at the Highland Park Bridge interchange. The new lane will address congestion and the existing bottleneck allowing for two lanes of free flow traffic from Kittanning to Pittsburgh. Additionally, the ramp from Virginia Avenue Extension to southbound Route 28 has reopened.

From 2009 to 2014, five major projects totaling more than $100 million in part, addressed the traffic bottlenecks at the 31st and 40th Street bridges. The improvements, which allowed for free flow traffic leaving Pittsburgh, then pushed the bottleneck to the High Park Bridge interchange. The $47.31 million project will help mitigate congestion by establishing two lanes in each direction on mainline Route 28 at the interchange and enhance safety with improved acceleration and deceleration lanes at the bridge.

Work will continue on Route 28 through January as crews conduct sign installation, sound wall work, and barrier and bridge sealing.  Off-peak traffic restrictions will occur as the work continues.  

Please allow extra time and use caution when traveling through the work zone.
