Legacy Parkway (designated as State Route 67, SR-67) is an four-lane controlled-access parkway located almost completely within Davis County in the northern part of the U.S. state of Utah. The parkway travels north from Interstate 215 (I-215) in northwestern Salt Lake City to an interchange named the Wasatch Weave in Farmington with two intermediate interchanges providing access to Woods Cross and Centerville. Wetlands of the nearby Great Salt Lake and nature preserves border the western side of the parkway while the eastern side roughly parallels Union Pacific and Utah Transit Authority rail lines and I-15. Construction began in 2006 and was completed in 2008, with the parkway opening in September of the same year. The parkway was controversial in its construction and was challenged in court several times before a compromise was met between the state and the Sierra Club, which limited the speed on the road and banned trucks on the highway except in emergencies. In addition to the restrictions on speed and trucks, the road was reduced from a six-lane expressway to a four-lane parkway. On average, between 20,000 and 23,000 vehicles use the parkway daily. ==Route description== The parkway begins at an incomplete interchange with I-215 in extreme northern Salt Lake County near the Jordan River Off-Highway Vehicle State Recreation Area. The interchange allows motorists from the Interstate to transfer onto Legacy Parkway and travelers to access I-215 southbound. After about , Legacy Parkway enters Davis County, and heads northerly with two lanes in each direction through semi-rural Woods Cross. The parkway then turns northeasterly and back north again, meeting 500 South at a diamond interchange, which also provides a connection to Redwood Road (SR-68). The eastern border of the Legacy Nature Preserve is formed by the parkway as it travels north. In West Bountiful, the parkway curves to the northeast as it follows the contour of the wetlands which lie on the western side of the road. Before reverting to its original northerly direction, the route intersects Parrish Lane (SR-105) at another diamond interchange. Past the intersection, Union Pacific and Utah Transit Authority (FrontRunner) railroad tracks run between the parkway and I-15 to the east. For the remainder of the parkway's length, I-15 is located approximately east. Upon entering Farmington, the parkway gains one lane in each direction and terminates at a triple-junction with I-15, SR-225 and U.S. Route 89 west of Lagoon. This interchange is referred to as the Wasatch Weave. The design of the road was re-envisioned to include extensive wetland protection west of the parkway and in the parkway median, a trail system along the side of the parkway,〔 and numerous pedestrian overpasses and underpasses for ease of access to the trail system. Many of the architectural features were also specially-designed to give the parkway a more unique feel. There are a total of of protected areas to the west of the highway, and an additional of wetlands along the length of the highway.〔 The Legacy Nature Preserve lays along the western border of the parkway near its southern terminus. Further north, the parkway forms much of the eastern border of the Farmington Bay Waterfowl Management Area. For the entirety of the parkway's length it is paralleled by the Legacy Parkway Trail, and is partially paralleled by the Denver and Rio Grande Western rail trail.〔 Every year, the Utah Department of Transportation (UDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), a measure of traffic volume for any average day of the year. In 2012, UDOT calculated that as many 22,955 vehicles used the highway on an average day near its junction with 500 South, and as few as 20,240 vehicles used the highway at its southern terminus at I-215. The Federal Highway Administration classifies Legacy Parkway as a MAP-21 Principal Arterial. 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「Legacy Parkway」の詳細全文を読む スポンサード リンク
