 I @-@ 87 begins in the Bronx at the northern approach to the Triborough Bridge , where it connects to the Bruckner Expressway ( I @-@ 278 ) at a directional T interchange . The route heads west from the interchange , paralleling loosely with the Harlem River through Mott Haven . After 1 mile ( 1 @.@ 6 km ) , the highway makes a turn to the north , mirroring a change in the nearby river 's course . It passes by Yankee Stadium on its way to Highbridge , where the Deegan connects to the Cross Bronx Expressway ( I @-@ 95 and U.S. Route 1 or US 1 ) at the eastern approach to the Alexander Hamilton Bridge . The Deegan remains in close proximity to the Harlem River until the waterway turns westward at Kingsbridge to form the northern edge of Manhattan .
