Northbound Route 28 to Open to Two Lanes at the Highland Park Bridge Interchange Today in Allegheny County


Pittsburgh, PA – PennDOT District 11 is announcing northbound Route 28 will open to two lanes of unobstructed traffic at the Highland Park Bridge interchange in Sharpsburg and Aspinwall boroughs, Allegheny County today, Friday afternoon, December 15 weather permitting.

A newly constructed northbound lane will open on mainline Route 28 at the Highland Park Bridge interchange at approximately 5 p.m. today. The new lane will address congestion and the existing bottleneck allowing for two lanes of free flow traffic from Pittsburgh to Kittanning.

“It is very exciting to reach this milestone of Route 28 having two lanes of unrestricted free flow traffic after generations of transportation professionals have worked collectively on this effort for decades,” said District Executive Jason Zang, P.E. “We thank the men and women who worked day and night, in adverse weather conditions, next to speeding traffic to deliver this final major improvement on Route 28.”

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 continues on southbound Route 28 as crews guide rail installation, sawing and sealing operations, and line painting. The new southbound lane is anticipated to open to traffic next week if weather permits.

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