| Interstate 37 (i37) is a 143.0-mile
intrastate Interstate Highway located
within Texas. The highway was first designated in 1959
as a route between Corpus Christi and San Antonio.
Construction in the urban areas of Corpus Christi and
San Antonio began in the 1960s and the segments of the
Interstate Highway in rural areas were completed by the
1980s. Prior to i37, the route between Corpus Christi
and San Antonio was served by a combination of State
Highway 9 (SH 9) from Corpus Christi to Three Rivers and
U.S. Route 281 (US 281) from Three Rivers to San
Antonio. As a result of the construction of i37, SH 9
was removed from the State Highway System. |

| The highway begins in Corpus Christi
at US 181 and SH 35 and heads north to San Antonio,
where it ends at i35. Beyond i35, the freeway continues
as US 281 to northern San Antonio as a major freeway. In
Corpus Christi, the highway provides access to the
downtown area, the Port of Corpus Christi, and the
Corpus Christi International Airport. In San Antonio, it
provides access to Downtown, Brooks City-Base, the
Alamodome, the Tower of the Americas, the River Walk,
the Alamo, and by extension via US 281, the San Antonio
International Airport. The route provides an important
connection between i35 and the Texas Gulf Coast as
well as one of the few limited-access hurricane
evacuation routes away from the southern Texas coast. |
