  How long is the drive from San Antonio to Corpus Christi?,About 145 miles on I-37. Free-flow is about 2 hours 10 minutes; realistic is 2 hours 15 to 2 hours 45 minutes. Pattern estimates, not live times.
  Is there an alternative to I-37?,US 181 via Beeville runs a parallel course. Slower and more rural. Worth taking only if I-37 is closed or you want a change of scenery.
  When is San Antonio to Corpus Christi traffic worst?,The San Antonio end in the morning peak or evening return, plus summer weekends and spring break beach traffic. Sunday afternoon northbound in beach season is the worst regular return slot.
  Where should I stop between San Antonio and Corpus Christi?,Pleasanton (~35 miles), Three Rivers (~75 miles, the midpoint), and Mathis (~110 miles). Do not leave San Antonio on a quarter tank.
  How do I get to Port Aransas from this drive?,The ferry from Aransas Pass is free but queues significantly in peak season — an hour or more on a summer Saturday is normal. The causeway via Corpus Christi and Padre Island is longer but avoids the wait.
