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
2017, there were 1,004 centerline miles and 3,384 lane miles
of state-maintained roadways in Bexar County. In 2018, the San Antonio
urbanized area had 258 centerline miles and 1,435 lane miles of
freeway; this ranked 22nd nationwide for both categories, but ranked
16th for lane miles per capita and for percentage of local
roads (3.2%) that are
freeways. Just over 50% of all local traffic is carried on the freeway
system, which ranks seventh 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. (For the
boundaries of what is covered, see the primer
page.) Below,
you'll find links to general information about the local freeways,
their history, and pages with in-depth details about each
freeway. There are also details
of the major freeway construction projects, and information about
TransGuide and other ancillary aspects of the local freeway system.
