Like most cities in Texas,
San Antonio was served by a loop around the city long before the arrival of the
Interstate Highway System.
Loop 13, although not a freeway, served in this role up until the 1950s, when many of San Antonio's freeways were constructed. The northern half of Loop 13 followed the current path of I-410 while the southern half still exists on the south side of San Antonio. Much of the freeway was proposed during the mid-1950s with construction beginning on the northwest portion of the loop near I-10. On October 15, 1960, Loop 13 from I-10 to I-35 was redesignated as Loop 410 for continuity purposes. By 1961, the freeway had been completed from I-35 on the southwest side to just east of US 281 near the airport, where it continued once to the east as a four-lane highway to I-35. By 1964, the southern arc had been extended eastward from I-35 to Roosevelt Avenue and was under construction from Roosevelt Avenue to I-35 on the east side of the city. By 1967, the eastern arc had been completed to
Interstate Highway standards, and the remaining portion from US 281 to I-35 on the city's north side had been completely built to Interstate Highway standards but still carried the Loop 410 designation until July 31, 1969, when it officially became I-410. officially called the "San Antonio Web". ==Exit list==
