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 a.m. 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.
The Three Rivers Heritage Trail will remain open near the bridge – on the North Shore and Downtown – for the duration of the project.
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.
