I-579 Overnight Improvements Continue this Week in Pittsburgh


Pittsburgh, PA – PennDOT District 11 is announcing overnight improvement work on I-579 for the I-579 “Cap” Urban Connector project in the City of Pittsburgh, Allegheny County, will occur Wednesday and Thursday nights, September 11-12 weather permitting.

Crews from the Joseph B. Fay Company will conduct overhang and parapet removal work and hang overhead jacks from 8 p.m. to 6 a.m. requiring the following restrictions: 

  • Wednesday night, September 11 – Southbound I-579 single-lane restriction

  • Thursday night, September 12 – I-579 single-lane restriction in each direction

The work is part of the $29.34 million project which will consist of the construction of a structure spanning I-579 to link downtown Pittsburgh and the Hill District. In part, the Cap project will create a new three-acre greenspace which will include pedestrian pathways, bicycle routes, rain gardens for stormwater management, and design elements from neighborhood artists. Additional construction activities include retrofitting existing retaining walls and bridges to accommodate the new structure, roadway reconstruction, drainage improvements, traffic signals, highway lighting, ITS, and landscaping.
