This article is about the only Interstate currently numbered 410. For former routes numbered 410, see Interstate 410 (disambiguation).

Interstate 410 (abbreviated I-410) is a loop route of Interstate 10 that runs around San Antonio, Texas. On exit signs, it is identified as Connally Loop in honor of former Texas governor John B. Connally. The north and west section of I-410 is currently undergoing a major expansion to ten lanes (five in each direction) from Culebra Road to the I-35 interchange as well as major interchanges being renovated at Bandera Road, Interstate 10 and San Pedro Avenue, as well as an interchange being installed at the junction with U.S. 281 near San Antonio International Airport.

[edit] Route description

Interstate 410 circumnavigates the city of San Antonio, officially begining and ending at the junction with Interstate 35 on the southwest side of the loop. There are vast differences between the northern arc and southern arc of the loop. The northern arc serves the heavily urbanized portions of San Antonio and is currently being upgraded to as many as five lanes in each direction. The southern arc resembles more of a rural interstate as it transverses for the most part undeveloped portions of San Antonio as a two lane interstate. I-410 intersects I-10 twice, I-35 twice, I-37 once, as well as U.S. Highway 90, U.S. 281, and State Highway 151, all freeways in the San Antonio metro area. I-410 serves San Antonio International Airport, Lackland AFB, Fort Sam Houston, South Texas Medical Center, Southwest Research Institute, and Toyota Motor Manufacturing Texas.

[edit] History

As most cities in Texas, San Antonio was served by a loop around the city long before the arrival of the Interstate Highway System. State Highway 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. In 1960, Loop 13 from I-10 to I-35 was redesignated as State Highway Loop 410 for continuity purposes. By 1961, the freeway had been completed from I-35 on the southwest side to just east of U.S. 281 near the airport, where it continued on to the east as a 4-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 to I-35 on the east side of the city. By 1967, the eastern arc had been completed to interstate standards and the remaining portion from U.S. 281 to I-35 on the cities northside had been completely upgraded to interstate standards, but still carried the State Loop 410 designation until 1969 when it officially became Interstate 410.

Due to the city growing primarily to the north, I-410 required upgrading along this stretch. It was expanded to six lanes in the late 1970s and early 1980s from Ingram Road to I-35 North. It was further expanded to six lanes from Ingram to Valley Hi Road in 1987. An additional westbound lane was added from I-10 West to Babcock Road in 1996.
