Construction Project Spotlight: I-579 Cap Urban Connector Project

The I-579 Cap Urban Connector Project (also known as the Cap Project) will consist of the construction of a new “cap” park structure spanning over a portion of I-579. The Cap Project is bounded by Washington Place, Centre Avenue, Chatham Street, Bigelow Boulevard and land to the north of Bigelow Boulevard.

HDR Engineering is the designer/engineer for this project. The City of Pittsburgh is holding the construction contract and the Sports and Exhibition Authority is coordinating with the City on the administration of the project. PennDOT is responsible for construction management and oversight, with sub-consultants supporting construction management and inspection. Upon completion, the City of Pittsburgh will own and maintain the Cap Park.

A Notice to Proceed for construction was issued on June 24, 2019. Construction completion is anticipated for November 2021. As of November 15, 2021, Governor Wolf and local, state, and federal officials held a ribbon cutting ceremony to announce the upcoming completion of the Cap Urban Connector project. For more information about the ribbon cutting event and the significance of this project, read PennDOT’s article from early December 2021.

Northbound I-579 Ramp to 7th Avenue Set to Reopen A Week Early On Thursday Morning, July 29, After Being Closed for 700 Consecutive Days

PennDOT District 11 is announcing the reopening of the ramp that carries traffic from northbound I-579 to 7th Avenue in the City of Pittsburgh, Allegheny County is anticipated to occur Thursday morning, July 29 weather permitting.

The ramp from northbound I-579 to 7th Avenue is expected to reopen to unobstructed traffic at approximately 8 a.m. Thursday morning. As part of the I-579 “Cap” Urban Connector project, the ramp was closed to traffic for nearly 700 consecutive days beginning on September 6, 2019. The ramp is reopening a week early.

The long-term closure was required for pier construction within the limits of the ramp to support the bridge cap structure. A total of four piers were constructed. The work included deep foundation work consisting of 42 caissons drilled to a depth of 35 feet, 42 new concrete columns which support four pier caps that range from 86 to 106 feet in length to support the 126 pre-stressed adjacent box beam bridge. Additional work performed during the long-term closure included the reconstruction of drainage and pavement structure on the ramp, installation of a new highway lighting system under the bridge, and the staging of equipment and material for access and work on the structure and park.

Remaining work on the project includes underdeck lighting installation, milling and paving operations, and installation of park items including sidewalks, artwork, and lighting. This work, and seeding and planting, will continue through November 2021. Restrictions on I-579, local roadways, and various ramps will continue through the remainder of the project.

Approximately 2,250 vehicles use the ramp each day. 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.
