DESIGNER: HNTB Corp.
CONTRACTOR: Williams Brothers

San Antonio will soon have one of the largest spurs in the U.S. This four-level, fully directional interchange should definitely urge motorists to move. The project includes the addition of eight direct connection ramps and approximately 7.9 centerline miles of freeway, cross street, ramp and ITS improvements. Working next to the airport capped the height of the structure so as not to impose on air navigation restrictions. This required the use of “framed-in” caps.
