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 second largest
state highway system next to 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 Interstate Highways, U.S. Highways, and state 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 that are 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
I-10's inside the state borders to Spur 200 at just long.
