The Major Deegan Expressway (officially the Major William Francis Deegan Expressway) is a north–south expressway in the New York City borough of the Bronx. It is the southernmost 8.38 miles (13.49 km) of Interstate 87 (I-87), beginning at I-278 at the interchange of the Bruckner Expressway and the Triboro Bridge in the south Bronx and ending at the Westchester County line in Yonkers, where the New York State Thruway begins. In between, the Major Deegan Expressway winds through Van Cortlandt Park, intersects with I-95 (the Cross Bronx Expressway) near the George Washington Bridge, and passes by Yankee Stadium on its eastern flank.

The expressway was opened in 1956 and became part of I-87 when that highway was assigned as part of the creation of the Interstate Highway System in 1957. Commonly known as "The Deegan", it is named for William Francis Deegan, who was a Major in the Army Corps of Engineers and a Democratic political leader in New York City.

History

Overhead signage for the expressway

The origins of the Major Deegan Expressway date back to 1936 when the Regional Plan Association concluded that in order to relieve New York City's traffic problems, a limited-access, truck-accessible expressway should be built on the west side of the Bronx. This route would connect the brand-new Triborough Bridge to the proposed New York State Thruway in Westchester County. A 1.5 miles (2.4 km) section of the expressway from the bridge to the Grand Concourse was completed in April 1939. The highway was adorned with Whitestone-style light posts placed every 75 feet (23 m) of the 6-lane highway, each of which were 12 feet (3.7 m) in width.^[2] The expressway was designated as NY 1B ca. 1941;^[3][4][5] however, the designation was removed by 1947.^[6]

In 1945, public works planner Robert Moses proposed extending the highway to the proposed Thruway. The plan began to come along in 1950,^[2] as the lower part of Tibbets Brook—located alongside the New York and Putnam Railroad—was put underground to make room for the new highway.^{[citation needed]} The present alignment was opened in 1956^[2] and became part of I-87 when that highway was assigned as part of the creation of the Interstate Highway System in August 1957.^[7]

In the wake of former New York Yankees player Joe DiMaggio's death on March 8, 1999, Governor George Pataki proposed renaming the Deegan Expressway to the "Joe DiMaggio Highway". However, New York City Mayor Rudolph Giuliani favored renaming the West Side Highway for DiMaggio instead.^[8] A week later, Pataki agreed to Giuliani's proposal.^[9]
