Fuel stations cluster along I-35 and I-20, but become sparse on US-90 west of Comstock. Fill up in Del Rio or Marathon, where distances between pumps exceed 60 miles. Gas prices in Texas average $3.20 per gallon (2024), lower than Oklahoma's $3.40. A typical sedan will cost about $70-80 for the one-way trip. Tolls exist on parts of I-35 near Dallas; have cash or a transponder.

• Best fuel stops: Ardmore, OK (exit 24) and Cisco, TX (exit 235).
• Road quality: I-35 has heavy truck traffic; US-90 is well-maintained but narrow in spots.
• Estimated driving time: 8-9 hours, plan for 10 with breaks.

Wildlife collisions peak at dawn and dusk on US-90; watch for javelinas and cattle. Speed limits drop to 65 mph in construction zones. Rest areas are plentiful on I-35 but vanish on US-90. Use the Texas Travel Information Center in Llano for maps. Families will enjoy the Science Mill in Johnson City and the Caverns of Sonora. Pets are welcome at most roadside parks; carry water and shade.
