Document Description
Caltrans proposes to conduct drilling at the Trinity River Bridge (bridge number 05-0028). A planning study has been prepared that identifies constructing outrigger piers to mitigate for future scour. It is proposed that the structure be supported on pile foundations at the supports. The purpose of the drilling is to generate subsurface geotechnical data essential for the design of the proposed bridge retrofit. The borings will consist of 94-mm diameter, vertical mud rotary soil borings located in or around the vicinity of the proposed supports of the retrofit for the bridge. Phase 1 of the drilling identifies four boreholes from the bridge deck.
