Rachel Carson (Ninth Street) Bridge Closes Monday, 2/11/19, for Long-Term Rehabilitation Project through Early August 2020

The Department of Public Works announced today that the Rachel Carson (Ninth Street) Bridge in the City of Pittsburgh will close to vehicle and pedestrian traffic beginning at 6 AM on Monday, February 11, 2019. The closure, which is expected to last through summer 2020, is required for a $23.3 million rehabilitation project.

Traffic will be detoured using the Andy Warhol (Seventh Street) Bridge and Isabella Street.

Major items of work during the project include:

  • New Concrete Deck
  • Structural Steel Repairs
  • Painting of the bridge Aztec Gold
  • Replacement of the bridge lighting with architectural lighting similar to the original
  • Replacement of the bridge expansion dams and drainage systems
  • Replacement of the sidewalks

The bridge will have a new lane configuration when it reopens. Instead of four lanes of traffic with two lanes in each direction, there will be three lanes of traffic with wider shoulders. When traveling into downtown from the North Shore, one lane will lead onto the bridge and widen out to two lanes at Fort Duquesne Boulevard. Similarly, when traveling from downtown to the North Shore, one lane will lead onto the bridge and then widen into two lanes on the other side.

The project will be completed by Brayman Construction as well as Advantage Steel and Construction, both of Saxonburg, and is being done in conjunction with PennDOT and the Federal Highway Administration.

The Rachel Carson Bridge was opened in 1926 and is one of the three “Sister Bridges,” the only trio of identical bridges in the world and the first self-anchored suspension bridges in the United States. This is the second rehabilitation project of the three “Sister Bridges,” following the Andy Warhol (Seventh Street) Bridge, which reopened in November 2017. Rehabilitation of the Roberto Clemente (Sixth Street) Bridge is expected to occur between summer 2021 and winter 2022.

PennDOT District 11 is reminding motorists the long-term closure of the ramp that carries traffic from northbound I-579 to 7th Avenue in the City of Pittsburgh, Allegheny County begins Friday, September 6 weather permitting.

As part of the I-579 “Cap” Urban Connector project, the ramp from northbound I-579 to 7th Avenue will close to traffic at approximately 8 p.m. Friday, September 6 for 700 consecutive days through August 6, 2021. Crews will place concrete barriers at the ramp, southbound I-579 will be shifted into two 11-foot wide lanes, and line painting operations will occur through Saturday morning. Approximately 2,250 vehicles use the ramp each day.

The long-term closure is required for pier construction within the limits of the ramp to support the bridge cap structure. A total of four piers will be constructed. The work includes deep foundation work consisting of 42 caissons drilled to a depth of 35 feet, 42 new concrete columns which will support four pier caps that range from 86 to 106 feet in length to support the 126 pre-stressed adjacent box beam bridge.
