Document Description
The California Department of Transportation (Caltrans) proposes a bridge scour maintenance project at the Interstate 405 (I-405) / Interstate 605 (I-605) interchange - a complex of three (3) bridges that traverse the San Gabriel River at the Los Angeles County/Orange County line. Two of the three bridges exist within the jurisdiction of Caltrans District 7 - Los Angeles (Bridge No. 53-1185 and Bridge No. 53-1737H from post mile 0.2/0.3), and the third bridge exists within the jurisdiction of Caltrans District 12 - Orange County (Bridge No. 53-413F at post mile 24.11). The scope of work for all three bridges includes 1) retrofit of bridge substructure foundation by constructing pier footing extensions at Pier 3 and Pier 4 at each bridge, 2) reinforcement of new footing extensions through placement of new Cast-In-Drilled-Hole (CIDH) piles, and 3) armoring of substructure retrofit through placement of rip-rap/rock protection around each pier.
