Getting Around Texas: Transportation Guide & Travel Tips

Texas contains 268,596 square miles of land area, making transportation infrastructure essential for movement between its widely separated population centers and natural features. The state maintains 313,210 total roadway miles according to the Texas Department of Transportation, the largest state-maintained road network in the United States. Interstate highways form the primary arteries connecting major cities, with I-35 running north-south through Austin and San Antonio, I-45 linking Houston and Dallas, I-10 traversing the southern portion from El Paso through San Antonio and Houston to the Louisiana border, and I-20 crossing the northern tier from near Odessa through Dallas to Louisiana. Interstate 37 connects San Antonio to Corpus Christi on the Gulf Coast. These routes handle the majority of intercity passenger vehicle traffic and commercial freight movement.

The distance between Texas cities determines practical transportation choices. Houston sits 165 miles east of Austin, 239 miles east of San Antonio, 243 miles south of Dallas, and 747 miles east of El Paso. Dallas lies 195 miles north of Austin, 274 miles north of San Antonio, and 625 miles northeast of El Paso. San Antonio sits 80 miles southwest of Austin and 544 miles southeast of El Paso. El Paso occupies the westernmost position in the Trans-Pecos region, separated from other major population centers by hundreds of miles of desert and mountain terrain. These distances make personal vehicle use dominant for intercity travel, with air travel becoming the practical choice for routes exceeding 300 miles or when time constraints apply.

Commercial aviation serves Texas through 27 airports with scheduled passenger service. George Bush Intercontinental Airport in Houston handled 44.45 million passengers in 2019, operating as a United Airlines hub with direct international routes to destinations across Central America, South America, Europe, and Asia. Dallas/Fort Worth International Airport processed 75.07 million passengers in 2019, functioning as the primary hub for American Airlines with extensive domestic and international connectivity. Austin-Bergstrom International Airport served 17.7 million passengers in 2019, experiencing growth driven by technology sector expansion in the capital. San Antonio International Airport handled 10.5 million passengers in 2019, serving both tourism and military-related travel. William P. Hobby Airport, Houston's second facility, processed 15.8 million passengers in 2019, operating primarily Southwest Airlines domestic routes. El Paso International Airport connects the Trans-Pecos region with 3.5 million annual passengers. These facilities provide jet service on routes where driving time exceeds three to four hours, with Houston-Dallas, Houston-Austin, Houston-San Antonio, Dallas-Austin, Dallas-San Antonio, and Dallas-El Paso among the highest-frequency corridors.

Amtrak operates three routes touching Texas territory. The Texas Eagle runs from Chicago through St. Louis and Little Rock to San Antonio via Dallas, Fort Worth, Austin, and intermediate stops, continuing three days per week to Los Angeles as a through service. The Sunset Limited operates three days per week between New Orleans and Los Angeles, serving Houston, San Antonio, Del Rio, Sanderson, Alpine, and El Paso within Texas. The Heartland Flyer provides daily service between Oklahoma City and Fort Worth. These routes serve limited city pairs and operate with frequencies unsuitable for time-sensitive travel, making rail a niche option for specific passenger preferences rather than a competitive intercity mode. No commuter rail connects separate Texas cities, though individual metropolitan areas operate local systems.

Personal vehicle ownership rates in Texas exceed national averages due to geographic spread and limited public transit outside core urban areas. The Texas Department of Motor Vehicles registered 22,779,744 vehicles in 2020 across a population of approximately 29 million, yielding roughly 0.78 vehicles per capita including all age groups. Gasoline prices vary by location and market conditions, with Gulf Coast proximity generally producing lower prices than inland areas. Major highways outside metropolitan regions typically provide fuel stations at intervals of 20 to 50 miles, though Trans-Pecos routes including I-10 west of San Antonio and US-90 contain segments exceeding 70 miles between services. Drivers planning routes through Big Bend, the Guadalupe Mountains, or the Llano Estacado should verify fuel availability at planned stops.

Rental car agencies operate at all commercial airports and in downtown locations of major cities. Daily rates vary by location, vehicle class, and booking timing, with airport locations typically adding facility fees ranging from 10 to 20 percent of the base rate. Minimum age requirements range from 21 to 25 years depending on company and vehicle type, with drivers under 25 often assessed additional daily surcharges. Insurance requirements mandate liability coverage, available through rental companies or personal auto policies. Texas law requires minimum liability coverage of 30,000 dollars per injured person, 60,000 dollars per accident, and 25,000 dollars for property damage. Visitors should verify whether personal insurance or credit card benefits provide adequate coverage for rental vehicles before purchasing company-offered policies.

Urban public transit systems operate independently in major cities with no integration between metropolitan areas. Austin's Capital Metropolitan Transportation Authority runs bus routes throughout the city and a commuter rail line called the MetroRail, operating 32 miles between Leander and downtown Austin with nine stations. Dallas Area Rapid Transit operates the nation's longest light rail system at 93 miles, serving Dallas, Richardson, Plano, Garland, Irving, and other municipalities with four lines, plus commuter rail service to Fort Worth through Trinity Railway Express. Metropolitan Transit Authority of Harris County provides bus service throughout Houston and 23 miles of light rail on three lines serving downtown, the Museum District, the Texas Medical Center, and surrounding neighborhoods. VIA Metropolitan Transit operates bus routes throughout San Antonio without rail service. Fort Worth Transportation Authority runs bus routes and partners with Dallas in the Trinity Railway Express commuter rail operation. These systems serve specific urban cores and immediate suburbs but do not connect separate cities, limiting usefulness for visitors moving between destinations.

Intercity bus service operates primarily through Greyhound and several regional carriers. Greyhound maintains routes connecting major Texas cities with multiple daily departures on high-traffic corridors like Houston-Austin-San Antonio and Dallas-Fort Worth-Austin. Smaller operators including Tornado Bus Company, Turimex Internacional, and El Expreso provide service emphasizing routes to the Mexico border and between Texas cities with significant Hispanic populations. Bus travel offers the lowest-cost intercity option but requires significantly longer journey times than driving due to multiple stops and route structures. The Houston-Austin trip requires approximately three to four hours by bus compared to two and a half hours of direct driving time.

Cycling infrastructure varies dramatically by location. Austin maintains approximately 500 miles of on-street bike lanes, off-street paths, and shared-use trails, with downtown areas providing dedicated infrastructure on several major streets. Houston has expanded its network to approximately 500 miles of bikeways, though much of this consists of shared-lane markings rather than protected facilities. Dallas operates approximately 160 miles of off-street trails and 200 miles of on-street facilities. San Antonio provides approximately 500 miles of various bicycle facilities, though connectivity between neighborhoods remains incomplete. Rural highways in Texas typically lack shoulders wide enough for safe cycling, and traffic speeds on state highways commonly reach 75 to 80 miles per hour, creating hazardous conditions for bicycle travel between cities. The Hill Country west of Austin and roads around Palo Duro Canyon attract recreational cyclists, but long-distance bicycle touring requires careful route planning to avoid high-speed corridors without shoulders.

Ride-hailing services including Uber and Lyft operate in all major Texas cities following state legislation in 2017 that preempted local regulations. These services provide airport transfers, intracity travel, and late-night transportation in urban cores. Availability decreases substantially in rural areas and small towns, where traditional taxi services may not exist. Pricing uses dynamic algorithms that increase rates during high-demand periods, with airport rides and Friday or Saturday night service typically commanding premium rates. Tipping conventions generally suggest 15 to 20 percent for satisfactory service.

The Gulf Coast presents specific transportation considerations. Padre Island National Seashore requires four-wheel-drive vehicles for beach driving beyond the first five miles of North Beach and along most of the 60-mile undeveloped shoreline. Galveston Island is accessible via I-45 and a causeway, with downtown and beach areas navigable by conventional vehicles. Corpus Christi serves as the gateway to Padre Island and Mustang Island, connected by the John F. Kennedy Causeway and State Highway 358.

Big Bend National Park requires private vehicle access as no public transportation serves the area. The nearest commercial airports are Midland International Air and Space Port, 236 miles northeast, and El Paso International Airport, 325 miles northwest. State Highway 118 provides access from Alpine, while US Highway 385 approaches from Marathon and Fort Stockton. The park encompasses 801,163 acres with the Chisos Mountains in the center, the Rio Grande forming the southern boundary, and unpaved roads accessing remote areas. The Ross Maxwell Scenic Drive to Castolon and Santa Elena Canyon requires 60 miles round trip from park headquarters at Panther Junction. The road to Boquillas Canyon adds another 50 miles round trip. Primitive roads including Old Maverick Road and River Road require high-clearance vehicles and four-wheel drive depending on recent weather.

Guadalupe Mountains National Park sits 110 miles east of El Paso via US Highway 62/180, with no services within park boundaries. The nearest fuel and lodging exist in Whites City, New Mexico, 35 miles north, or Dell City, Texas, 40 miles west. The park contains 86,367 acres and focuses on day hiking and backcountry camping rather than scenic driving.

West Texas distances create specific fuel and service considerations. US Highway 90 between Sanderson and Marathon spans 61 miles without services. Interstate 10 between Fort Stockton and Van Horn covers 141 miles with one fuel stop at Kent, operating irregular hours. US Highway 385 from Marathon to Fort Stockton runs 68 miles through uninhabited range country. Drivers should carry water, verify fuel tank capacity against planned routes, and account for limited cell phone coverage across much of the Trans-Pecos region, the Llano Estacado, and areas of South Texas.
