Document Description
Caltrans proposes to perform a complete bridge replacement of the Russian River Bridge (Bridge #10-182) and Redwood Valley Road Undercrossing (UC) (Bridge #10-183) on a new alignment, located along SR-20 in Mendocino County near Ukiah between post miles (PM) 33.3 to 34.4. To insure traffic would not be significantly impeded during construction, the existing structures and alignment would remain in place during construction. This would require that the new structure be on a new alignment south of the existing alignment. The alternatives involve additional work such as embankment cut/fill, paving bridge approaches, roadway realignment, and shoulder widening. Each alternative proposes the addition of acceleration and deceleration lanes with standard tapers for the intersection of SR-20 and County Road (CR) 144. Currently, the bridge deck has numerous transverse cracks leaving the bridge susceptible to punching shear failure.
