In the
United States, each state maintains its own system of
state highways.[a] This is a list of the longest state highways in each state. As of 2007[update], the longest state highway in the nation is
Montana Highway 200, which is 706.624 miles (1,137.201 km) long. The shortest of the longest state highways is
District of Columbia Route 295, which is only 4.29 miles (6.90 km) long.
^Some states internally number the
Interstate Highways and
U.S. Highways within their state as state highways; these are not counted in the list.
^DC-295 is the only non-national route in the district.
^The multiple segments of
FL A1A consist Florida's longest signed state highway, but
FL 5 (the almost entirely unsigned designation for the
US 1) is longer at 536.724 miles (863.774 km)
