Transforming Freeways into Parks
In 1968, San Antonio celebrated its 250th birthday with HemisFair ’68, a six-month international exhibition that took years to build and attracted 6.4 million visitors. It was built on a 92-acre site on the southwestern edge of downtown that had previously been a residential area with historic homes and small shops. Some streets were removed, creating long superblocks. The fair included temporary exhibits, a convention center and 750-foot-tall Tower of the Americas with rotating restaurant on top.
