Title

Marsh Creek Detention Facility Bridge Replacement Project

Description

Project is limited to the replacement of an existing detention facility bridge over Marsh Creek and adjustment of 300 feet of roadway to accommodate the new bridge. The new bridge will be a 60 foot long, cast in place, pre-stressed concrete bridge with one 12 foot wide traffic lane and two, 2 foot wide shoulders with single beam barriers rails on both sides. The bridge will span Marsh Creek with no support piles in the creek bed. The creek will be graded 40 feet in the downstream end and require the installation of 60 linear feet of rock slope protection on both banks, and require the installation of a 120 linear feet temporary culvert system. A temporary road will be installed in the creek while the new bridge is being constructed. The Project is located at 12000 Marsh Creek Road in the city of Clayton, Contra Costa County, California. The CDFW is executing a Lake and Streambed Alteration Agreement No. 1600-0327-R3 pursuant to Section 1602 of the Fish and Game Code to the project Applicant, Contra Costa County Public Works Department.
