Antonio Area Freeway System
page last updated January 2, 2018
Since the first
expressway opened in 1949, the
metropolitan area has enjoyed one of most progressive and comprehensive
urban freeway systems in North America. For many 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
one of the largest systems of state highways in the nation and one of
the highest ratios of freeway miles per capita in the US. In
2014, there were 1,004 centerline miles and 3,384 lane miles
of state-maintained roadways in Bexar County. Approximately
centerline miles and 1,900 lane miles of that total were
freeways. A study by the Surface
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,
