Tips for driving in San Antonio

The major San Antonio highways are in a wagon wheel pattern, with I-410 and Hwy. 1604 forming loops around the city, and highways U.S. 90, U.S. 87, U.S. 281, I-35, I-10, and I-37 acting as the spokes. Frontage roads run parallel to the highways and make great alternatives during rush hour, with convenient turnarounds if you need to go the opposite direction. The frontage roads do tend to flood during rainstorms, so keep your eye on the weather and plan accordingly!
