PennDOT District 11 is announcing the I-579 “Cap” Urban Connector project in the City of Pittsburgh, Allegheny County, will resume operations Tuesday, April 28 weather permitting.

The $29.34 million project 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. For additional details on the project including information on sustainability, funding, and public input please visit http://www.pgh-sea.com/LHR-i579cap.htm.

Overnight lane and shoulder restrictions will resume from 8 p.m. to 6 a.m. weeknights beginning Tuesday night between the Bedford Avenue and Webster Avenue bridges starting in the northbound direction. Restrictions will occur in both directions for foundation work but not simultaneously. A weekly schedule will be provided.
