Built in 1890, the Strawberry Hill Avenue Railroad Bridge supports four tracks of the New Haven Line (NHL). The bridge replacement falls under the Connecticut Department of Transportation's (CTDOT) TIME (Track Improvement Mobility Enhancement) program, which is being executed along the NHL to reduce commuter travel times.

The Strawberry Hill Avenue Railroad Bridge project replaces the existing bridge superstructure and updates the
supporting structure underneath while maintaining the current vertical and horizontal clearances.

The superstructure replacement will be built in halves during the construction of the WALK Bridge, allowing work to be performed during planned two-track outages for the WALK Bridge replacement. This project is coordinated with the other TIME-2 railroad improvement projects at East Avenue, Fort Point Street, and Osborne Avenue.

Site preparation, mobilization, and support of excavation work started in late 2023. Construction activities began in the fall of 2024.
