The City of Pittsburgh's bridges safely and efficiently connect 90 distinct neighborhoods into one unified community where we live, work, and play. Their unrivaled scale, variety, and history are recognized worldwide and have proudly earned us our status as “The City of Bridges.”

Our bridges link us back to our industrial heritage while enabling transportation for our residents and visitors to Pittsburgh. Whether they cross a secluded park trail or the banks of the Monongahela River, each has a unique design and purpose.

The Department of Mobility and Infrastructure (DOMI) is responsible for the oversight and maintenance of 143 bridges owned by the City of Pittsburgh. Our bridges reflect Pittsburgh's long tradition of ingenuity and ambition, which is why we are ramping up our capital projects to rehabilitate and modernize our bridge inventory to propel Pittsburgh into the future.

The Capital Bridge Project Hub is intended to provide an insight into the projects and work our teams and partners perform everyday. While we don't have a unique Engage Page for every project, many of the bridge projects provide residents the ability to leave feedback and ask questions for our teams.

Tentative work is scheduled on the following:

• Bloomfield Bridge
• Shaler Street Bridge (Minotte Square) over Saw Mill Run
• Panther Hollow Road over Panther Hollow
  • Inspection and analysis of this bridge has been extended into Spring 2026 due to challenges with access and the complexity of the structure
  • The design of repairs is well underway and we intend to start construction as soon as Summer 2025
• Wilksboro Avenue Pedestrian Bridge

Projects in the design phase are advancing through one of two stages: preliminary engineering or final design.

During the preliminary engineering phase, our team of engineers are actively conducting site surveys, traffic analyses, evaluating geotechnical soil parameters, inspecting and analyzing existing conditions, evaluating how to maintain utilities during construction, identifying detours, and evaluating the project for constructability.

Once a project enters final design, all of the preliminary engineering tasks are polished and refined, and the engineers compile hundreds of engineering drawings which are then checked and rechecked before a final bid package is delivered. Depending on the bridge type, surrounding environmental factors, whether the project is considered historic, as well as a multitude of other challenges for the team to consider, the estimated design timeline may require 3-5 years.

Be sure to frequently check a project page to review updates, receive announcements, and to engage with the project team where your input can help guide the process!

The following bridge projects are advancing through either preliminary engineering or final design phase:

Additional projects include:

• Herron Avenue Bridge Rehabilitation

Projects in the planning phase means our team is actively working with PennDOT and the Southwestern Pennsylvania Commission (SPC) to identify and secure funding, establish a tentative scope of work, and contract with engineers for the design of each project. Due to the nature of the contracting process, from the time we identify a candidate project to the time engineering begins often requires 18-24 months. With this in mind, our teams work to identify and prioritize critical projects early on to minimize life-cycle costs and avoid potential disruptions to the surrounding communities.

The following bridge projects have been identified by DOMI for a major capital investment in the form of either a rehabilitation or preservation project.

• McArdle Roadway Bridge over East Sycamore Street Preservation
• McArdle Roadway Bridge at Grandview Avenue Rehabilitation
• East Sycamore Street Bridge Preservation
• Corliss Tunnel Rehabilitation
