The Hampton Roads Beltway is a loop of Interstate 64 and Interstate 664, which links the communities of the Virginia Peninsula and South Hampton Roads which surround the body of water known as Hampton Roads and comprise much of the region of the same name in the southeastern portion of Virginia in the United States. The Hampton Roads Beltway crosses the harbor of Hampton Roads at two locations on large four-laned bridge-tunnel facilities. The Hampton Roads Bridge-Tunnel carries Interstate 64 (and U.S. Route 60) and the Monitor-Merrimac Memorial Bridge-Tunnel carries Interstate 664. The entire beltway, including the bridge-tunnels, is owned and operated by the Virginia Department of Transportation. ==History== Even before Interstate 64 was built beginning in 1958, from some of the earliest planning stages, there were hopes of a circumferential highway to Interstate highway standards for the Hampton Roads region. Some proposals envisioned state and local and/or toll funding if necessary to achieve that goal. Indeed, the first two-laned portion of the Hampton Roads Bridge-Tunnel was built with toll revenue bond funding in 1957 prior to the creation of I-64. It carried U.S. Route 60 and State Route 168 designations, and tied in with the new Tidewater Drive in Norfolk. (Tolls were removed when the other two lanes and tunnel were built adjacently to the immediate south of the older structure with federal Interstate Highway funding in the mid 1970s.) Building of Interstate 64 was the first priority in the region, and a portion of Interstate 264 through Portsmouth connecting with the Downtown Tunnel was completed even as I-64 finally reached its eastern terminus at Bower's Hill in Norfolk County (which became the City of Chesapeake in 1963). I-64, the portion of the Hampton Roads Beltway which was completed first, makes a huge long arc around the area, from Hampton through portions of Norfolk, Virginia Beach, and Chesapeake and around Portsmouth to reach Bower's Hill at the edge of the Great Dismal Swamp. It was a number of years before the newer I-664 portion was built. The roadway connects with I-64 at Bower's Hill in Chesapeake and crosses through portions of Portsmouth and Suffolk to cross Hampton Roads via the Monitor-Merrimac Memorial Bridge-Tunnel and then pass through eastern Newport News to reconnect with I-64 in Hampton. This completed the loop in 1992. In January, 1997, a -long I-64/I-664 loop was designated by the Virginia Department of Transportation (and signed) as the Hampton Roads Beltway. 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「Hampton Roads Beltway」の詳細全文を読む スポンサード リンク
