Colorado State Highways

The system of State highways in Colorado is a system of public paved roads funded and maintained by the Colorado Department of Transportation (CDOT) in the U.S. state of Colorado. These comprise state highways (typically abbreviated SH), U.S. Routes, and Interstate Highways. The numbered highways within the state begin at 1 and increase, with exception of numbers already designated as U.S. highways or Interstate Highways. In 1953, many highways were decommissioned or lost mileage. Before the 1968 Colorado state highway renumbering, highways were cosigned with U.S. highways and Interstate Highways, and there were highways matching U.S. Highway and Interstate Highway numbers.

Interstate Highway System United States highway system

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. Construction of the system was authorized by the Federal Aid Highway Act of 1956. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico.

United States Numbered Highway System Highway system of the United States of America

The United States Numbered Highway System is an integrated network of roads and highways numbered within a nationwide grid in the contiguous United States. As the designation and numbering of these highways were coordinated among the states, they are sometimes called Federal Highways, but the roadways were built and have always been maintained by state or local governments since their initial designation in 1926.

Numbered highways in Ohio Highway system of Ohio in the United States

The Ohio Department of Transportation (ODOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes. As with other states, U.S. and Interstate highways are classified as state routes in Ohio. There are no state routes which duplicate an existing U.S. or Interstate highway in Ohio.

Interstate 225 (I-225) is a 11.959 mile (19.246 km) connector spur route of Interstate 25 in Colorado. It is the only auxiliary route of Interstate 25, and one of two auxiliary Interstate highways in the state of Colorado. I-225 traverses Aurora and small portions of Denver and Greenwood Village. It runs north from Interstate 25 in the Denver Tech Center to Interstate 70 north of Aurora. It interchanges with state highway 83, state highway 30 and Interstate 70 Business/U.S. Highway 40/U.S. Highway 287, known locally as Colfax Avenue. Construction on the freeway began in 1964 at the I-70 interchange and continued progressively through many years proceeding south through Aurora until final completion in 1976 with the final link between Yosemite Street and I-25.

The state highway system of the U.S. state of Oregon is a network of highways that are owned and maintained by the Highway Division of the Oregon Department of Transportation (ODOT).

Texas state highways are a network of highways owned and maintained by the U.S. state of Texas. The Texas Department of Transportation (TxDOT) is the state agency responsible for the day-to-day operations and maintenance of the system. Texas has the largest state highway system, followed closely by North Carolina's state highway system. In addition to the nationally numbered Interstate Highways and U.S. Highways, the highway system consists of a main network of state highways, loops, spurs, and beltways that provide local access to the other highways. The system also includes a large network of farm to market roads that connect rural areas of the state with urban areas and the rest of the state highway system. The state also owns and maintains some park and recreational roads located near and within state and national parks, as well as recreational areas. All state highways, regardless of classification, are paved roads. The Old San Antonio Road, also known as the El Camino Real, is the oldest highway in the United States, first being blazed in 1691. The length of the highways varies from US 83's 893.4 miles (1,437.8 km) inside the state borders to Spur 200 at just 0.05 miles long.

Interstate 270 (I-270) is a 7-mile-long (11 km) highway in the northeastern part of the Denver–Aurora Metropolitan Area in the U.S. state of Colorado. It overlaps U.S. Highway 36 (US 36) for its entire length. The western terminus of I-270 is at the interchange with I-25 and US 36. It heads eastward to an interchange with I-76, where the mileposts reset because of a previous freeway extension. The freeway heads southeast and comes to meet Vasquez Boulevard, where it enters Commerce City. The road crosses Quebec Street before ending at I-70.

Interstate 70 (I-70) is a transcontinental Interstate Highway in the United States, stretching from Cove Fort, Utah, to Baltimore, Maryland. In Colorado, the highway traverses an east–west route across the center of the state. In western Colorado, the highway connects the metropolitan areas of Grand Junction and Denver via a route through the Rocky Mountains. In eastern Colorado, the highway crosses the Great Plains, connecting Denver with metropolitan areas in Kansas and Missouri. Bicycles and other non-motorized vehicles, normally prohibited on Interstate Highways, are allowed on those stretches of I-70 in the Rockies where no other through route exists.

U.S. Highway 75 (US 75) is a part of the U.S. Highway System that travels from Interstate 345 (I-345) in Dallas, Texas northward to the Canada–US border at Noyes, Minnesota. In the state of Texas it runs from I-345 in Dallas and heads north to the Oklahoma state line.

U.S. Route 6 in California U.S. highway in California

U.S. Route 6 (US 6) is a transcontinental United States Numbered Highway, stretching from Bishop, California, in the west to Provincetown, Massachusetts, in the east. The California portion of US 6 lies in the eastern portion of the state from Bishop in the Owens Valley north to the Nevada state line in Mineral County. Prior to a 1964 Highway renumbering project US 6 extended to the Pacific Ocean in Long Beach, California, as part of the historic auto trail named the Grand Army of the Republic Highway.

In the U.S. state of Pennsylvania, state highways are generally maintained by the Pennsylvania Department of Transportation (PennDOT). Each is assigned a four-digit State Route (SR) number in the present Location Referencing System. Traffic Routes are signed as Interstate Highways, U.S. Routes and Pennsylvania Routes, and are prefixed with one to three zeroes to give a four-digit number. PA Routes are also called Pennsylvania Traffic Routes, and formerly State Highway Routes.

U.S. Route 95 (US 95) is a United States Numbered Highway, stretching from the Mexican border in San Luis, Arizona to the Canadian border near Eastport, Idaho. The California portion of US 95 traverses through the far eastern edges of both Riverside and San Bernardino counties. US 95 serves Blythe and Needles and junctions with SR 62 at Vidal Junction.

Interstate 87 (I-87) is a partially completed Interstate Highway in the U.S. state of North Carolina, currently the shortest designated primary Interstate Highway at 12.9 miles (20.8 km). The completed portion is in eastern Wake County, between Raleigh and Wendell; the majority of the completed route is known as the Knightdale Bypass, while the remaining 3 miles (4.8 km) follows the Raleigh Beltline. It is planned to continue northeast through Rocky Mount, Williamston and Elizabeth City, ending in Norfolk, Virginia. It is signed as north-south, in keeping with the sign convention for most odd-numbered interstates, but the route goes primarily east-west, with the eastern direction aligning to the north designation. The entire route is concurrent with US 64, with portions also concurrent with I-440 and US 264.

Delaware State Route System Overview of the State Route System of Delaware

The Delaware State Route System consists of roads in the U.S. state of Delaware that are maintained by the Delaware Department of Transportation (DelDOT). The system includes the portions of the Interstate Highway System and United States Numbered Highways system located in the state along with state routes and other roads maintained by DelDOT. All roads maintained by the state are assigned a maintenance road number that is only marked on little white markers at intersections and on auxiliary plates below warning signs approaching intersections. These numbers are only unique in a specific county; some roads can be designated with multiple road numbers, and numbers do not necessarily correspond to the signed Interstate, U.S., or state route numbers. DelDOT maintains a total of 5,386.14 miles (8,668.15 km) of roads, comprising 89 percent of the roads within the state. Some large bridges in the state are maintained by other agencies including the U.S. Army Corps of Engineers and the Delaware River and Bay Authority. Roads in the system include multilane freeways, multilane surface divided highways, and two-lane undivided roads serving urban, suburban, and rural areas. Some of the roads maintained by DelDOT are toll roads, in which motorists must pay to use.
