Interstate 287 (I-287) is an auxiliary Interstate Highway in the US states of New Jersey and New York. It is a partial beltway around New York City, serving the northern half of New Jersey and the counties of Rockland and Westchester in New York. I-287, which is signed north–south in New Jersey and east–west in New York, follows a roughly horseshoe-shaped route from the New Jersey Turnpike (I-95) in Edison Township, New Jersey, clockwise to the New England Thruway (I-95) in Rye, New York, for . Through New Jersey, I-287 runs west from its southern terminus in Edison through suburban areas. In Bridgewater Township, the freeway takes a more northeasterly course, paralleled by U.S. Route 202 (US 202). The northernmost part of I-287 in New Jersey passes through mountainous surroundings. After crossing into New York at Suffern, I-287 turns east on the New York State Thruway (I-87) and runs though Rockland County. After crossing the Hudson River on the Tappan Zee Bridge, I-287 splits from I-87 near Tarrytown and continues east through Westchester County on the Cross-Westchester Expressway until it reaches the New England Thruway. A bypass around New York City had been planned since the 1950s and would become a part of the Interstate Highway System and receive the I-287 designation. The Cross-Westchester Expressway, which was originally designated as Interstate 187, opened in 1960 as Interstate 487 before later becoming part of I-287. The New York State Thruway portion of I-287, which included a crossing of the Hudson River, opened in 1955. In New Jersey, the proposed I-287 had originally been designated as FAI Corridor 104 and incorporated what was planned as the Middlesex Freeway. The New Jersey section of I-287 between the New Jersey Turnpike in Edison and US 202 in Montville opened in stages between the 1960s and 1973; the remainder opened in 1994. The aging Tappan Zee Bridge is due to be replaced with a new span — construction started in 2013, with opening scheduled for 2017. In addition, a proposed tunnel across the Long Island Sound between Rye and Oyster Bay on Long Island would link the eastern terminus of I-287 to New York State Route 25 (NY 25) and NY 135 in Syosset. ==Route description== |- |NJ || 67.54 || 108.70 |- |NY || 31.18 || 50.18 |- |Total || 98.72 || 158.87 |} 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「Interstate 287」の詳細全文を読む スポンサード リンク
