Cheapest Gas Stops on I-35 Between San Antonio and Dallas
Drivers heading from San Antonio to Dallas on I-35 can save money by knowing where to fill up along the route.
Motorists making the roughly 275-mile drive from San Antonio to Dallas along Interstate 35 have several opportunities to save at the pump, with gas prices varying noticeably from one corridor city to the next. Knowing when and where to stop can mean the difference of several dollars on a full tank, a meaningful consideration as fuel costs remain a persistent pressure on household budgets.
The I-35 corridor passes through a string of mid-sized Texas cities and towns — including San Marcos, Austin, Georgetown, Waco, and Hillsboro — each with its own local fuel-price dynamics.
