State roads in New Mexico, along with the Interstate Highway System, and the United States Numbered Highway System, fall under the jurisdiction of the New Mexico Department of Transportation (NMDOT). The U.S. state of New Mexico has 412 state roads, totaling 7,405.762 miles (11,918.419 km) that criss-cross the 33 counties of the state.[a] Most highway numbers are one, two, or three digits long, however there are three highways that have four digit highway numbers. These highways are New Mexico State Road 1113 (NM 1113), NM 5001, and NM 6563.
There are 26 state roads that are shorter than one mile (1.6 km) long in the state. The shortest, NM 446, is a quarter-mile (402 m) long and serves to connect Valmora to NM 97.[1] NM 597, the second shortest highway, links U.S. Route 160 (US 160) to the Four Corners Monument, a tourist destination on the Navajo Nation where the states of Utah, Arizona, New Mexico, and Colorado meet.[2] In comparison, the longest state road in New Mexico is NM 120, 119.031 miles (191.562 km) long, which is more than 475 times longer than the shortest state road.[1]
