PRECAST WALL SYSTEM CUTS TIME

The report describes how an abutment of the Continental St. highway bridge over the Santa Cruz River near Tucson, Arizona was repaired when flash flooding washed out the abutment. The bridge is a cantilever arch the abutment is non-bearing. A 261-ft. X 16-ft. retaining wall was designed that would notch into the top of a soil cement slope protection structure of nearly equal depth and 8-ft. thickness. slope protection was built stair fashion, 1/2:1, in 6-in. lifts. More than half of the soil cement work lay below streambed level; granular material from its excavation provided backfill of the retaining wall.
