The Cross Bronx Expressway is a major freeway in the New York City borough of the Bronx. It is mainly designated as part of Interstate 95 (I-95), but also includes portions of I-295 and U.S. Route 1 (US 1). The Cross Bronx begins at the Alexander Hamilton Bridge over the Harlem River, where the Trans-Manhattan Expressway continues west across Upper Manhattan to the George Washington Bridge. While I-95 leaves at the Bruckner Interchange in Throgs Neck, following the Bruckner Expressway and New England Thruway to Connecticut, the Cross Bronx Expressway continues east, carrying I-295 to the merge with the Throgs Neck Expressway near the Throgs Neck Bridge. Though the road goes primarily northwest-to-southeast, the nominal directions of all route numbers west of the Bruckner Interchange are aligned with the northbound route number going southeast, and the southbound route number going northwest. The Cross Bronx Expressway was conceived by Robert Moses and built between 1948 and 1972. It was the first highway built through a crowded urban environment in the United States; the most expensive mile of road ever built to that point is part of the Cross Bronx, costing $40 million (). At one point during construction, Moses' crews had to support the Grand Concourse (a major surface thoroughfare), a subway line and several elevated train lines while the expressway was laboriously pushed through. The highway experiences severe traffic problems, and its construction has been blamed for negatively affecting a number of low-income neighborhoods in the South Bronx. Route description The Cross Bronx Expressway begins at the eastern end of the Alexander Hamilton Bridge as a continuation of the Trans-Manhattan Expressway and officially designated as both I-95 and US 1. Immediately after coming off the bridge, there is an interchange with the Major Deegan Expressway (I-87) for Yankee Stadium and points upstate. The highway soon intersects with Webster Avenue at a partial interchange allowing eastbound vehicles to exit and westbound ones to enter. Northbound US 1 leaves the Cross Bronx Expressway at this exit. About later, the expressway has a pair of closely spaced interchanges for New York State Route 895 (NY 895, Sheridan Boulevard) and the Bronx River Parkway. The exit for Sheridan Boulevard is an incomplete interchange and allows access from northbound and to southbound I-95 only. The Cross Bronx Expressway reaches the Bruckner Interchange later. The service road is called East 177th Street between the Bronx River
