Document Description
The California Department of Transportation (Permittee) proposes to conduct the following: Horse Creek Bridge – Location 1, the Project is limited to the following; implement traffic control, installation of cut-off walls, repair of concrete spall, and installation of staging and access areas. Install temporary access road and staging areas, install temporary creek diversion system (TCDS). Add Portland cement concrete cut-off walls at both sides of Abutment 2 and the right side of Abutment 1. Cut-off walls will extend down 5 feet below existing grade, backfill abutments and wingwalls with approximately 4,875 square feet of rock slope protection (RSP) (0.25-T-size rocks approximately 2 feet deep). Repair concrete spalling on deck, remove TCDS and install erosion control.
McCune Creek Bridges – Location 2. remove one willow tree and one Chinese elm tree, located north of the westbound bridge at McCune Creek. Implement traffic control during the installation of the pile jackets, replacement of the longitudinal joint seals between the old and new structures, replacement of the lateral joint seal, repair of the concrete spalling, and installation of staging and access areas. Install temporary access road and staging areas. Install TCDS, excavate as needed and rebuild abutment slope embankments with engineered backfill and place RSP from the toes of slopes up to the abutment pile caps to prevent erosion. Pressure-pump grout or cement from underneath the deck or use of shotcrete to fill voids at the abutments. Once all the voids are filled, install RSP up to the pile cap/bridge soffit. Excavate 5 feet maximum around the columns at the bents. Install a fiberglass reinforced polyester and concrete jacket to the 30 existing, exposed 16-inch-diameter Raymond piles, new pile diameter will be 26 inches. Concrete will be pumped into the new pile jacket to fill the void between the new pile surface and the existing Raymond pile. The fiberglass reinforced polyester jackets will be installed up to 5 feet below original grade. Replace longitudinal and lateral joint seals on the bridge superstructure. Repair concrete spalling on deck. Remove TCDS, install erosion control and landscaping.
