The Unionport Bridge, a double-leaf bascule drawbridge crossing Westchester Creek, is a vital piece of South Bronx infrastructure that supports 60,000 vehicles daily. Built in the 1950s, the bridge was in poor condition due to age and heavy traffic, leading the New York City Department of Transportation (NYCDOT) to undertake its full replacement, including new mechanical, electrical, and fender systems. The new bridge comprises two side-by-side, single-leaf bascules, each carrying three lanes, a bikeway, and sidewalk.
