Pittsburgh, PA – 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
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.
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. For additional details on the project including information on
