In the United States each state maintains its own state highway system. This is a list of the shortest state highways in each state.
State Route 72 is a 36.74-mile-long (59.13 km) state highway in the U.S. state of Arizona. It runs from SR 95 near Parker southeast to U.S. Route 60 in Hope. Along its route in La Paz County, the highway is mostly parallel to the Arizona and California Railroad and runs through the community of Bouse in desert terrain. The route was established in 1930 from its current eastern terminus all the way to the California state line, but was truncated in 1965. The route was completely paved by 1940.
U.S. Highway 8 (US 8) is a United States Numbered Highway that runs primarily east–west for 280 miles (451 km), mostly within the state of Wisconsin. It connects Interstate 35 (I-35) in Forest Lake, Minnesota, to US 2 at Norway in the Upper Peninsula of Michigan near the border with Wisconsin. Except for the short freeway segment near Forest Lake, a section near the St. Croix River bridge, the interchange with US 51, and a three-mile (4.8 km) stretch west of Rhinelander, Wisconsin, it is mostly an undivided surface road. As a state highway in the three states, US 8 is maintained by the Minnesota, Wisconsin and Michigan departments of transportation.
U.S. Route 167 is a north-south United States Highway within the U.S. states of Louisiana and Arkansas.

State Route 92 is a state highway in the U.S. state of Arizona. Running roughly in an L-shaped pattern, SR 92 begins at SR 90 in Sierra Vista and ends at a traffic circle in Bisbee along SR 80, running entirely within Cochise County. The route was constructed and numbered as SR 92 in the late 1930s with a route that traveled further north past Sierra Vista than it does today. The routing was corrected in the 1960s.

US 730 travels east along the Columbia River as a continuation of Columbia River Highway No. 2 into Umatilla County, intersecting I-82 and US 395 in the city of Umatilla. US 730 and US 395 form a short concurrency within the city before the highways part, and US 730 continues northeast into Washington.

Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.
