Interstate 610 is a freeway that forms a loop around the city of Houston, Texas.
History
The concept of building a bypass highway around Houston was first proposed in 1931, but plans did not begin to formalize until 1941. The loop was initially proposed to transport troops and materials around the city. On May 3, Harris County voters approved a bond to build the "Defense Loop". It was officially designated as Loop 137 in 1942, and the North Loop was approved by the Texas Transportation Commission . However, World War II delayed construction of the Loop until the 1950s.
In July 1953, the city of Houston asked the Texas Transportation Commission to include 2 new sections of Loop 137 (the West Loop and the South Loop) as part of the state's highway system. It was initially rejected, but in October 1954, the North Loop was upgraded to a freeway, and the West and South Loops were approved as freeways.
When the interstate highway system was authorized in 1956, the then C-shaped Loop 137(now designated Interstate 610) was adopted into the plan. The East Loop would not be approved until 1960.
Construction on the North Loop began in 1950. Construction was sporadic throughout the 1950s and 1960s. It was completed in 1976 with the interchange that connects Loop 610 to Interstate 10 east of Houston.
