Built in 1894, the Osborne Avenue Railroad Bridge supports four tracks of the New Haven Line. The Walk Bridge Program replaces the existing Osborne Avenue bridge superstructure and rehabilitates the substructure while maintaining the current vertical and horizontal clearances. The replacement is built in halves during construction of the Walk Bridge, allowing work to be done during planned two-track outages for the Walk Bridge replacement.
A new sidewalk and under-bridge lighting are planned along Osborne Avenue. Two 150-day closures of Osborne Avenue are anticipated to facilitate the bridge replacement. A projected detour map is available here.
Construction impacts to Osbourne Avenue will begin approximately 1.5 years into construction of the Walk Bridge Replacement Project.
