The $29.34 million project, sponsored by the City of Pittsburgh and the Sports and Exhibition Authority, consists 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.

The Joseph B. Fay Company is the prime contractor.

Work on this project will be in accordance with Centers for Disease Control and state Department of Health guidance as well as a project-specific COVID-19 safety plan, which will include protocols for social distancing, use of face coverings, personal and job-site cleaning protocols, management of entries to the jobsite, and relevant training.
