Title

State Route 4 Culvert Replacement

Description

Caltrans proposes to rehabilitate or replace existing culverts on State Route 4, 88, and 89 in Alpine County. Existing drainage systems at the proposed locations have exceeded their design life and have deteriorated or failed. Certain culverts would be replaced with the existing size, and others would be upsized to maintain existing water flow capacity. The project would also upgrade or replace end treatments and headwalls as needed. To maintain and upgrade the existing facilities, work off the paved roadway, ground disturbance, work in the channel, and vegetation removal would be required. Permanent right-of-way acquisition, temporary construction easements, and work on federal lands would be required.
