Kenmawr Bridge Replacement ​Project


Project Overview

The purpose of this project is to replace the structurally deficient and functionally obsolete Kenmawr Bridge, which carries South Braddock Avenue over the mainline tracks of the Norfolk Southern Railroad, between the Boroughs of Swissvale and Rankin, Allegheny County. The new structure will be raised to provide the necessary vertical clearance required for Norfolk Southern Railroad to run double-stacked trains, and the bridge will be lengthened to include a second span so as to accommodate future expansion plans by the P.A.A.C. for the Martin Luther King Jr. East Busway. The project will also include a new traffic signal and lane widening upgrades at the intersection of Woodstock & South Braddock Avenues, as well as drainage and guiderail updates, and all new signing and pavement markings. The project was successfully awarded to the lowest bidder, Golden Triangle Construction, at a cost of $12,465,520.45 and has a current completion date of 08/31/2021.

In an effort to maintain traffic, a temporary two-lane bridge with sidewalk will be constructed to the west of the existing structure, which will accommodate bidirectional vehicular traffic provide pedestrian access during construction. Due to the existing roadway approaches serving and maintaining two-way traffic during bridge construction, a short-term detour will be implemented during the reconstruction of the new roadway approaches to tie into the new structure. Bidirectional traffic will be maintained as long as feasible and an accelerated schedule will be implemented to minimize the detour time.

The proposed upgrades to Hawkins Village by the Allegheny County Housing Authority are not part of this project. A previous Public Meeting during the design phase of this project was held back in April of 2015.
