The South Lamar Boulevard Bridge in Austin, Texas, with its six open spandrel concrete arches,1 spans Lady Bird Lake. Constructed from 1940 to 1942,the bridge was the second permanent bridge to cross the Colorado River in Austin.

The South Lamar Boulevard Bridge was added to the National Register of Historic Places on July 7, 1994.2

Significant growth in Austin, especially south of the Colorado River, resulted in the South Lamar Boulevard Bridge becoming overburdened. Featuring ten-foot traffic lanes, narrow sidewalks and no provisions for cyclists, has led discussions on its rehabilitation or replacement.
