The Cross Bronx Expressway is a major freeway in the New York City borough of the Bronx, conceived by Robert Moses and built between 1948 and 1972. It carries traffic on Interstate 95 (I-95) through the city, and serves as a portion of I-295 toward Long Island; a portion is also designated 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 Extension continues east, carrying I-295 to the merge with the Throgs Neck Expressway near the Throgs Neck Bridge. The Cross Bronx Expressway was an engineering marvel, being the first highway built through a crowded urban environment; 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 at Westchester Av, Boston Rd, Third Av, and Jerome Av while the expressway was laboriously pushed through. The highway has severe traffic problems, and its construction has been blamed for devastating 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 one and half miles later, comes a pair of closely spaced interchanges for the Sheridan Expressway (I-895) and the Bronx River Parkway. The exit for the Sheridan Expressway is an incomplete interchange and allows access from northbound and to southbound I-95 only. The Cross Bronx Expressway reaches the Bruckner Interchange two miles (3 km) later. Going eastbound (I-95 northbound), the interchange allows access to southbound I-678, northbound I-95 (Bruckner Expressway) and southbound I-295. I-95 leaves the Cross Bronx Expressway here and continues north along the Bruckner Expressway. The Cross Bronx Expressway continues east of the interchange as I-295, which begins here. The Cross Bronx ends later at the Throgs Neck Expressway, where traffic from I-695 merges on towards the Throgs Neck Bridge.〔New York City Department of Transportation, (Truck Routes ), accessed November 2007: shows that the Cross Bronx Expressway Extension ends at the Throgs Neck Expressway, while the Throgs Neck Expressway continues to the Throgs Neck Bridge〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cross Bronx Expressway」の詳細全文を読む スポンサード リンク
