Demolition, site work, paving and new construction of a bridge / tunnel in Pittsburgh, Pennsylvania. Design plans call for the demolition of a bridge / tunnel; for the construction of a bridge / tunnel; for site work for a bridge / tunnel; and for paving for a bridge / tunnel.

The project is included in the FY2024-2029 Capital Improvement Plan. As of September 27, 2024, the project is in preliminary engineer through 2024. Final design is expected from 2025-2026 with construction anticipated to begin in 2027. *The closed solicitation has been included below for reference: The bridge carries 28th Street over two lanes of Sassafras Way, the Port Authority East Busway, and Norfolk Southern Railroad (NSRR) tracks and connects Liberty Avenue to Brereton Street (Polish Hill). Because the existing bridge is NHRP eligible, a Historic Bridge Rehabilitation Analysis will be required in addition to a Purpose and Needs statement to consider anticipated multi- modal usage. Depending on the findings of the Historic Bridge Rehabilitation Analysis, the scope of work will proceed for a rehabilitation or a replacement project. For a rehabilitation option, it is anticipated that the limits of work will extend from approach slab to approach slab (inclusive) with minor changes to the horizontal and vertical alignments, as needed. For a replacement option, the scope of work will include a task for alignment investigation in order to provide alternatives for improving the approach geometry at the north end of the structure as well as reducing the structure span length and considering anticipated usage, including bicyclist and pedestrians. The alignment investigation should provide vertical alignment that provides the minimum vertical clearance requirement for a railroad crossing. The City will be using the modified consultant selection process for securing the professional services. The anticipated Notice to Proceed is July 1, 2020. The method of contractor selection has not been determined at this time.
