Document Description
The California Department of Transportation (Caltrans) proposes immediate repairs of eroded embankments and damaged drainage flumes on northbound Interstate (I) 5 from Post Mile (PM) 13.3 to 14.0, and on westbound I-580 from PM 11.5 to 14.5, in San Joaquin County. On December 31, 2022, a high intensity rainstorm caused excessive runoff from the roadway to overwhelm the dikes and drainage inlets, eroding the embankment slopes and undermining the paved shoulders at several locations. The scope of work includes repairing the damaged embankments, replacing the damaged structural sections and Asphalt Concrete dikes, installing overside flume down drains, and installing erosion controls. All work will occur in Caltrans Right of Way. The purpose of this project is to ensure structural integrity of the roadway in these areas and avoid complete roadway failure. The project is needed to prevent the loss or impairment of life, property, or essential public services.
