The route passes through the westernmost municipality in the state, Murphy, and one of the most easternmost municipalities, Manteo, making US 64 a symbolic representation of the phrase "from Murphy to Manteo" which is used to refer to the expanse of the state. The highway is a major east-west route through the central and eastern portion of the state. ==Route description== US 64 enters North Carolina in Cherokee County, west of Murphy. The highway serves the cities of Hendersonville, Brevard, Rutherfordton, Morganton, Lenoir, Statesville, Lexington, Asheboro, Siler City, Raleigh, Rocky Mount, Tarboro, Williamston, and Manteo. The segment from Franklin to Highlands is a mountainous two-lane road limited to moderate-sized trucks. Large trucks are routed via Truck US 64 (US 23/441 and US 74) to Sylva, and Asheville. The route passes through Hendersonville, Chimney Rock State Park, and Forest City before turning in a more northerly direction towards Morganton, where it crosses I-40 for the first time. The route makes a wide, northerly loop past the Hickory area, and crosses I-40 again in Statesville. After crossing I-40 again in Mocksville, U.S. 64 makes a southerly bypass of the Piedmont Triad region. U.S. 64 is the primary east-west route through Randolph County and Chatham County, connecting the cities of Asheboro, Siler City and Pittsboro. In Pittsboro, the route divides, a newer bypass route follows a freeway north of the city while the older Business U.S. 64 goes through the center of the city along city streets, passing the Chatham County Courthouse. After Pittsboro, U.S. 64 crosses Jordan Lake in the community of Wilsonville before entering Wake County. In Wake County, a divided expressway carries U.S. 64 through Apex and Cary, with a mixture of grade-separated interchanges and at-grade intersections along this segment. In Cary, U.S. 64 joins U.S. 1 forming the heavily traveled U.S. 1-64 freeway which connects Cary and southwestern Wake County to Raleigh, the I-440 Beltline and I-40. Within the Raleigh city limits US 64 follows I-40. In 2006 a major section known as the Knightdale Bypass opened to ease traffic. After it was completed, US 64 became a continuous freeway as far east as Williamston, going through the communities of Nashville, Rocky Mount, and Tarboro. Closely paralleling this freeway segment, older alignments of US 64, following country roads and city streets, are known variously as Alternate US 64 (usually outside of city limits) and Business U.S. 64 (when inside of incorporated city limits). In Williamston, after forming a concurrency with both US 13 and US 17, it follows an exit ramp to become a four-lane undivided boulevard from Williamston to Plymouth, North Carolina. Between Plymouth and Columbia, North Carolina, the route is once again a freeway. From Columbia to its eastern junction with US 264 it is a two lane undivided highway through the swamps of Tyrell County. The route splits in Manns Harbor, North Carolina as Bypass US 64 uses the newer and wider Virginia Dare Memorial Bridge to cross Croatan Sound, bypassing Manteo to the south. The mainline route follows the older, narrower William B. Umstead Bridge and goes through the community of Manteo before rejoining the bypass route to access a series of bridges and causeways that connect Roanoke Island to Bodie Island on the Outer Banks. US 64 terminates at Whalebone Junction, a location in Nags Head that forms the three-way confluence of US 64, US 158 and NC 12. US 64 also make up part of Corridor A in the Appalachian Development Highway System (ADHS). Corridor A connects I-285, in Sandy Springs, Georgia, to I-40, near Clyde, North Carolina, it overlaps of US 64, between Hayesville and Franklin. ADHS provides additional funds, as authorized by the U.S. Congress, which have enabled US 64 to benefit from the successive improvements along its routing through the corridor. The white-on-blue banner "Appalachian Highway" is used to mark the ADHS corridor. US 64 overlaps with four state scenic byways: the Waterfall Byway, between Murphy and Rosman, Black Mountain Rag, centered at Bat Cave, Alligator River Route, between Columbia and Roanoke Island, and Roanoke Voyages Corridor, located on Roanoke Island.〔(【引用サイトリンク】title=NCDOT: Scenic Byways )〕 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「U.S. Route 64 in North Carolina」の詳細全文を読む スポンサード リンク
