Dillard Road Bridge Repair Project

The Sacramento County Department of Transportation (SACDOT) is seeking Requests for  Proposals (RFP) from prospective consulting firms for the placement of sheet piling or any alternate deep foundation design (primary and secondary piles/ jet grouting) at pier 3, and rock rip-rap in the riverbed underneath the Dillard Road Bridge over Cosumnes River.  The work shall include preparation of a Bridge Foundation Report, plans, specifications and estimates (PS&E), and calculations in accordance with Caltrans standards and Sacramento County design and construction details

The Dillard Road Bridge over Cosumnes River was originally built in 1964, and the bridge number is 24C0004.  The bridge is a 5-span, reinforced concrete (RC) T-girder superstructure, continuous on four (4) RC wall piers, and on two (2) RC diaphragm abutments.

Since the bridge was built, 10 ft of soil sediment underneath of the bridge has degraded.  This occurred due to agricultural activities (levee construction), in stream gravel mining, obstruction of sediment transport from two upstream low-flow dams near Rancho Murieta and Van Vleck Park (private), and the constriction of the bridge onto the floodplain.

The project site is located on Dillard Road over Cosumnes River, 0.2 MI south of Jackson Road (SR-16) in Sacramento County.
