Document Description
The California Department of Transportation (Caltrans) proposes to replace the existing southbound Willow Slough Bridge (Left Bridge–Bridge No. 24-0046L) with a new bridge on State Route (SR) 99 from post miles (PM) 6.04 to 7.06, approximately 6 miles north of the Sacramento and San Joaquin county line. The proposed scope of work includes constructing a new bridge at a higher elevation to match the existing northbound bridge elevation (Right Bridge–Bridge No. 24-0046R) at Willow Slough. The new Left Bridge will be designed to be raised in the future with the two bridges separated by a physical gap. In addition, this project would install Transportation Management System (TMS), remove the existing Thrie beam guardrail, and place a Type 842 Concrete Barrier for each bridge. The project would require one temporary construction easement (TCE); however, no acquisition of new permanent right of way is needed.
