Major Deegan Expressway

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 Triborough 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.
