The Bronx
The original 1916 plan for the Triborough Bridge placed the Bronx arm of the bridge at St. Ann’s Avenue and Southern Boulevard. The block was the southernmost tip of the New York mainland. At the time, the area was noted for its heavy industry and rail facilities. By 1927 the plan had shifted the Bronx terminal of the bridge a block east to Cypress Avenue and Southern Boulevard, which accommodated both vehicular traffic and planned rail improvements.
When the bridge opened in 1936, plans also included traffic connections in the form of an improved Bruckner Boulevard and Whitlock Avenue, as well as a future “westerly approach,” which later became the Major Deegan Expressway.
The Bronx span is notable for its convertible quality. Although the Bronx Kills was not navigable when the bridge was built, the bridge’s design allowed it to be retrofitted into a lift bridge in the future. Instead, several generations of fill have narrowed the waterway.
