The state highways in Harris County, Texas consists of approximately 1,213 miles (1,952 km) of routes in the Texas state highway system that are located within Harris County.[1] These highways are maintained by the Texas Department of Transportation (TxDOT). These highways are made up of Interstate Highways, U.S. Highways, State Highways, State Loop and Spur Highways, Farm to Market Roads, Park Highways, and Alternate and Business Routes. In addition to these highways, three independent Toll Roads and a section of Interstate 10 that is toll managed are also located in Harris County. These roads are maintained by the Harris County Toll Road Authority, and add approximately 120 miles (190 km) of highways to the overall Harris County highway system.[2]

There are currently four interstates located within Harris County. They consist of two major interstates (Interstate 10 (I-10), known as the Katy Freeway and East Freeway, and Interstate 45 (I-45), known as the Gulf Freeway and North Freeway), Interstate 69 and one Auxiliary Interstate (Interstate 610 (I-610), known as "The Loop"). There are also three U.S. Routes located in Harris County. These highways consist of U.S. Route 59 (US 59, known as the Southwest Freeway and the Eastex Freeway), U.S. Route 90 (US 90, known as the Cosby Freeway), and U.S. Route 290 (US 290, known as the Northwest Freeway). There are nine state highways, eight spur and loop highways, one park highway, four toll roads (three independent), twenty-two farm to market roads, four bannered U.S. routes, two bannered state routes, and one bannered farm to market road.

Highways

Interstate Highways and U.S. Highways

There are currently four interstate highways located in Harris County. Three of these are I-10, which runs west-east, I-45, which runs south-north, and I-610, which forms a small loop around Downtown Houston.[3][4] I-10 and I-45 run concurrently with each other for a short distance in Downtown Houston. All three highways were established in 1959, with the creation of the Interstate Highway System.[5][6][7] The fourth interstate, Interstate 69, runs concurrently with US 59 from the 610 North Loop to the Montgomery-Liberty county line, and was designated and signed in 2012. Eventually, US 59 inside the loop and west of the 610 west loop will also carry the I-69 designation, which will someday run from Brownsville, TX to Port Huron, MI.

In addition to the four interstate highways, there are also three U.S. Routes. These highways are US 59, which forms the Southwest and Eastex Freeways, and runs southwest-northeast, US 90, which runs concurrently with I-10 from the west county border to I-610, where it becomes the Cosby Freeway, running in a west-east direction, and US 290, which forms the Northwest Freeway, running southeast-northwest.[8][9]

State Highways, Loops, Spurs, and Park Roads

There are currently nine state highways located in Harris County. The longest of these is Texas State Highway 6, which stretches approximately 36.8 miles (59.2 km) from the Fort Bend County line to the Waller County line.[8][9][10] The shortest of these is Texas State Highway 35, which stretches approximately 6 miles (9.7 km) from the Fort Bend County line to Interstate 45 in south Houston.[11] NASA Road 1 is also located in Harris County, and is one of just two state highways in Texas that is not numbered. The other highway is State Highway OSR.[12]

There are currently only one loop highway in Harris County, Texas State Loop 494, which has its south end at I-69 just south of the Harris-Montgomery county line, and Beltway 8, the state's only highway designated as a beltway, forms a large loop around most of Houston.[13] There are six spur routes located in Harris County. The longest is Texas State Highway Spur 261, at 4.6 miles (7.4 km) long.[14] The shortest spur is Texas State Highway Spur 330, at 0.8 miles (1.3 km).[15] There is currently one park road located in Harris County, Texas Park Road 1836.[16] Park Road 1836 serves the San Jacinto Battleground State Historic Site and Battleship Texas. The highway is numbered 1836 to commemorate Texas's year of independence.[17] Park Road 1836 is 7.234 miles (11.642 km) long.[17]

Farm to Market Roads

There are currently twenty-two farm to market roads located in Harris County. Due to the heavy urbanization of Harris County, many of these FM's have been redesignated to Urban Roads under the TxDOT standards.[18] The length of these Farm to Market Roads varies from approximately 37 miles (60 km) long (FM 1960) to just 0.2 miles (0.32 km) (FM 1092).[19]

Toll Roads

There are five toll roads located in Harris County. Three of these toll roads are independent toll roads. These consist of the Hardy Toll Road, the Westpark Tollway, and the Fort Bend Toll Parkway. The other two toll roads are state-maintained highways that have been converted to toll highways. These are the Sam Houston Tollway (Beltway 8) and the Katy Managed Lanes, which is a section of Interstate 10 located between Katy and downtown Houston.[2] All toll roads are maintained by the Harris County Toll Road Authority, and are marked with a purple and yellow version of the county highway shield.[2]
