Interstate 410

Routing

Interstate 410 (Connally Loop) is a beltway around San Antonio. The northeastern quadrant overlaps with IH 35 between Kirby and Windcrest. SH 16 accompanies the western third of IH 410 from south San Antonio to Leon Valley. The state highway travels north from Zapata on the Rio Grande to U.S. 281 near Antelope, just south of Wichita Falls. The Interstate Route Log and Finder List does not attribute the overlapped mileage with IH 35 to IH 410. The zero milepost is located at the southwestern exchange with IH 35. Interchanges are numbered in a clockwise direction from that point.

The northern half of the Connally Loop, from U.S. 90 near Lackland Air Force Base to IH 35 at Windcrest is a heavily developed freeway. Suburban development extends outward from San Antonio toward the northwest and northeast along the IH 10, IH 35 and U.S. 281 corridors. South from U.S. 90 and IH 10, IH 410 runs along the periphery of San Antonio, with rural four lane stretches remaining.

History

Interstate 410 around San Antonio was constructed through the 1950s and 1960s. The first beltway section opened in 1958.1 IH 410 was added to the Interstate system as approved by the American Association of State Highway Officials (AASHO) on June 30, 1970.

Construction through 2006 modernized IH 410 between Interstate 10 and U.S. 281. Work widened the narrow, below-grade freeway and added a systems interchange with U.S. 281 (McAllister Freeway) by San Antonio International Airport (SAT). This exchange replaced a Breezewood connection between the two freeways along San Pedro Avenue to the west.
