Bruckner Expressway over Westchester Creek (Unionport Bridge)

Overview

This bridge, a relatively small but critical traffic connection, serves as not only an important local arterial and bus route, but also the only link between the Bruckner Expressway and Cross Bronx Expressway to the Hutchinson River Parkway and destinations north. The confined and challenging site is surrounded by the elevated Cross Bronx Bruckner Interchange.

The main bridge span is a “bascule” drawbridge that opens for navigation along the commercial waterway to accommodate critical oil deliveries and recreational boaters. The 65-year-old bridge, opened in 1953, is severely deteriorated from heavy traffic and its age. Historically, the bridge could not be taken out of service for any major repair due to its critical transportation function and has been forced to remain in continuous service.

The construction of the bridge must be carried out in 10 stages, and has a 48-month duration. The main construction challenge is keeping the busy waterway navigable and critical arterial route open while replacing the entire bridge. The plan to accomplish this difficult task includes constructing two temporary bridges to maintain vehicle traffic, erecting the final bascule span in an open position, and accomplishing all work in the navigation channel within a critical time frame.
