Document Description
This Project proposes to resurface the existing pavement on both mainline traveled ways and shoulders. The Project would replace existing K-rails located in the median with permanent concrete barriers type 60M, replace rumble strips along the shoulder and centerline, and replace existing MBGR with Midwest guardrail system (MGS). Standard gaps for wildlife crossing would be incorporated at regular intervals along the proposed MGS barriers according to the 2022 Caltrans’ Standard Plans, with the specific interval for these gaps and more detailed design to be developed during the Design and permitting phase of this Project in collaboration with regulatory agencies. The existing shoulders within the Project limits, currently between 7.0 and 7.5 feet wide, would be widened to 8 feet between PM 9.0 to PM 12.5. These shoulders would be signed and striped as bike lanes. The existing AC dikes that are within 7.0 to 7.5 feet of the existing edge of traveled way would be relocated to the edge of pavement to accommodate the standard 8-foot shoulders from PM 9.0 to PM 12.5. The Project would also upgrade the existing crash cushions to current standards and repair damaged drainage systems. At some locations along the highway, vegetation removal would be required for equipment staging and construction access. Two bridges along SR 12 within the Project area, the Union Creek bridge and Denverton Creek bridge, would also be upgraded to meet current Caltrans design standards.
