Parkville Road at Ash Creek Bridge (No. 06-0220) Replacement Project

The Parkville Road at Ash Creek Bridge Replacement Project, solicitation number 5A45CR00700, involves replacing the functionally obsolete bridge (No. 06-0220) in Shasta County, California, near Anderson. The project consists of constructing a new single-span, 102-foot-long by 27.5-foot-wide reinforced concrete cast-in-place post-tensioned box girder bridge on a new alignment south of the existing structure. To accommodate current traffic volumes and meet Shasta County and AASHTO standards, the scope includes widening roadway approaches from 16 to 22 feet, performing approximately 300 feet of approach road work on each side, replacing bridge railings with steel, and installing approach guardrails. Parkville Road will remain open during construction via a temporary detour using the existing bridge, which will be removed once the new structure is operational. The project has undergone environmental review under the California Environmental Quality Act (CEQA), resulting in a Mitigated Negative Declaration and a Notice of Determination confirming that the project will not have significant environmental effects provided that specific mitigation measures are implemented. Key environmental considerations include the protection of biological resources, specifically bat roosting habitats and migratory birds, as highlighted by the California Department of Fish and Wildlife. The contractor must adhere to strict hazardous waste protocols, including the proper labeling and disposal of treated wood waste according to California Code of Regulations Title 22 and the disposal of lead-based paint and asbestos at Class I landfills. The Shasta County Department of Public Works serves as the lead agency for this infrastructure improvement.
