Document Description
The California Department of Transportation (Caltrans) is formally initiating studies for an Initial Study/Environmental Assessment for the proposed improvements to the North Fork San Gabriel River Bridge (Bridge No. 53-2245). Two alternatives are proposed to mitigate the potential scour problem at the North Fork San Gabriel Bridge. Alternative 1 consists of scour mitigation, seismic retrofit, and bridge rail replacement. Additionally, this alternative proposes to construct steel column casings, footing retrofit with steel piles, retaining walls along the stream, check dams, and rock slope protection. Alternative 2 proposes a bridge replacement on the same alignment.
