Fourth Avenue, Between Wood Street and Smithfield Street, to Extend Full Vehicle Closure through the End of March

The City of Pittsburgh’s Department of Mobility and Infrastructure (DOMI) is extending the full vehicle closure of Fourth Avenue between Wood Street and Smithfield Street. This closure will be extended for the remainder of March due to unforeseen circumstances during construction.

During this time, all vehicle traffic will be detoured from Wood Street, to the Boulevard of the Allies, to Smithfield Street, to Fourth Avenue.

Port Authority Buses will be discontinued on Fourth Avenue and will utilize the Boulevard of the Allies for the temporary bus route during this closure. Pedestrian traffic will be maintained on Fourth Avenue throughout the project.

If you have any questions regarding this road closure, please submit them to the city’s 311 response center by dialing 311 within the city or 412-255-2621. They can also be submitted online at

Extended Closure Of Fourth Avenue Between Wood & Smithfield Streets – Extended Detour Circumventing Traffic & Property Issues – Street & Sidewalk Vault Repairs On The Exterior Of The Bank Building

The City of Pittsburgh has provided a permit to McKnight Realty and its prime contractor, Zottola Construction Company to close for an extended period of time a block of Fourth Avenue in Downtown Pittsburgh beginning on Thursday, February 6, 2020.

The property owner and its contractor will be performing street and sidewalk underground vault repairs and installation of a new sidewalk on Fourth Avenue between Wood & Smithfield Streets outside the Bank Building. Additionally, a permitted contractor on the opposite side of Fourth Avenue performing major upgrades at an adjacent structure by Franjo Construction, which has that sidewalk closed and one lane of Fourth Avenue restricted for over a year, will be allowed to continue work. The full street closure, which will then create a temporary pedestrian access in the middle of Fourth Avenue will begin on Thursday morning, February 6, 2020 and then last about thirty (30) days, or around Thursday, March 5, 2020.
Revision: Upon notification from the contractors on March 4, 2020, work has not been completed by either; thus the closure and the bus detours will continue effective Thursday, March 5, 2020, continuing until further notice. Due to the length of the closure, rerouting of all traffic on Wood and Smithfield Streets, and the inability to have ZipCar parking on Fourth at Smithfield relocated to accommodate the completion of bus turns, all buses for the duration must be temporarily detoured off of Fourth Avenue entirely.

Other routes affected: 56 – Lincoln Place, 57 – Hazelwood, 58 – Greenfield, 52L – Homeville Limited, 53L – Homestead Park Limited

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.

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.

Motorists traveling from the east into downtown Pittsburgh should consider using the Second Avenue (Exit 71B) or Grant Street (Exit 71A) off-ramps from inbound (westbound) I-376 (Parkway East).

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. Additionally, the contractor will stage equipment and material on the closed ramp for other project work including the bridge structure, highway lighting under the bridge, and the reconstruction of the ramp.
