:''This list covers state highways in Utah. For Interstates and U.S. Routes, see List of Interstate and U.S. Highways in Utah.'' The U.S. state of Utah operates a system of state routes that serve all portions of the state. The Utah Department of Transportation (UDOT) is responsible for maintaining all of the Interstate, U.S. Routes and state highways in the state. In official documents the state of Utah uses the term "state routes" for numbered, state maintained highways, since the legal definition of a "highway" includes any public road. UDOT signs state routes with a beehive symbol after the state's nickname of the beehive state. Most of the state routes are city streets and rural roads. However, there are a few state routes built to freeway or expressway standards, such as Bangerter Highway (SR-154) and State Route 201 in Salt Lake County, or the Legacy Parkway (SR-68) in Davis County and Southern Parkway (SR-7) in St. George. There are of state highways in Utah. The numbers and routes of all Utah highways are assigned by the state legislature, currently documented in Utah Code Title 72, Chapter 4. Most signed state highways in Utah are currently numbered between 7 and 280. Generally, state highways in Utah are clustered together, such as State Routes 7, 8, and 9 all in close proximity to the St. George area, or State Routes 118, 119, and 120 in the Richfield area. There is no specific numbering based solely on direction, aside from numbers used for U.S. and Interstate routes. To wit, State Routes 68 and 257 both run north-south and State Routes 21 and 30 both run east-west. Prior to 1977, route numbers 1-9 were among the numbers assigned as state designations for the U.S. and Interstate Highways that served Utah. Since 1969, the block of numbers between 281 and 320 has been reserved for routes serving state institutions and state parks. With a few exceptions, these routes do not have their numbers publicly posted. Two routes, State Route 900 and State Route 901, were created as "statewide public safety interest highways". There were two major changes to the Utah state route system, one in 1969, and the second change made in 1977. Since 1977, the legislative designations do not have any concurrencies. For the situations where two numbered roads share the same physical roadbed, one of the designations will have a discontinuity in the legislative designation. For example, Interstate 84 is defined as a highway with two separate segments in Utah code, the part where I-84 is signed concurrent with Interstate 15 is only legally designated I-15. The longest contiguous highway signed as a Utah State Route is State Route 24 at . The longest highway of any type in Utah is U.S. Route 89 at . The shortest state route is State Route 304 which is long, serving the Hyrum Lake State Park, though this route is unsigned. The shortest signed route is State Route 103 at long, serving Hill Air Force Base. Originally, the State Road Commission of Utah, created on 23 March 1909, was responsible for maintenance, but these duties were rolled into the new Department of Transportation in 1975.〔(【引用サイトリンク】title=Utah State Archives Catalog )〕 UDOT also maintains the Utah Scenic Byways system, which includes National Scenic Byways that travel through Utah. ==See also== *Utah Scenic Byways *1977 Utah state route renumbering *State highways deleted by the Utah State Legislature in 1969 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「List of state highways in Utah」の詳細全文を読む スポンサード リンク
