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.

Projects in the planning phase means our team is actively working with the Pennsylvania Department of Transportation (PennDOT) and the Southwestern Pennsylvania Commission (SPC) and the Federal Highway Administration (FHWA) to identify and secure funding, establish a 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 for the project to the time engineering begins often requires between 18 and 24 months. Our team members work to identify and prioritize critical projects early on the minimize life-cycle costs and avoid potential disruptions to the surrounding communities.

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

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 between 3 and 5 years

The part of the project that you can see: the construction process includes bidding and selecting contractors to perform the work as well as a period for engagement with the public during which the City shares details of project and how the work may impact the surrounding communities during active construction. This process takes around six months to complete. Active construction timelines depend on the condition and complexity of the bridge and surrounding environment, as well as any complications that arise during construction.
