Since the first expressway opened in 1949, the San Antonio metropolitan area has enjoyed one of most progressive and comprehensive urban freeway systems in North America. For many of those early years, San Antonio was second only to Los Angeles in the number of freeway miles. While most US cities now have extensive freeway systems, Bexar County still has one of the largest systems of state highways and freeways in the nation.
In 2021, there were 1,030 miles of state-maintained roadways in Bexar County. In 2020, the San Antonio urbanized area had 253 miles of freeway, which ranked 23rd nationwide. But the city ranked 17th for freeway lane miles per capita. Just under 50% of all local traffic is carried on the freeway system, which ranks 11th nationally. A study by the Surface Transportation Policy Project in 1998 ranked San Antonio's highways as the best among the largest US urban areas.
This site covers the San Antonio freeway system in depth. Below, you'll find links to general information about the local freeways as well as pages for each freeway discussing the various characteristics of the route along with a detailed history. There is also information about the major freeway construction projects, TransGuide, and other interesting ancillary aspects of the local freeway system.
