South Main Street and Soda Bay Road Widening and Bike Lanes Project

The South Main Street and Soda Bay Road Widening and Bike Lanes Project in Lake County, California, involves the rehabilitation and expansion of a roadway corridor located just south of Lakeport. The scope of work covers a 0.5-mile segment of South Main Street and approximately 0.8 miles of Soda Bay Road. Key infrastructure improvements include the construction of two 12-foot wide travel lanes, a continuous 12-foot wide center turning lane, and 8-foot wide paved shoulders designed as Class II bicycle facilities. Additional deliverables include the undergrounding of overhead utility lines, surface drainage improvements, and a safety correction to a horizontal curve on Soda Bay Road to increase its radius from 230 to 550 feet. The project is governed by CEQA and NEPA environmental standards, with recent addendums approved in November 2025 to allow for nighttime construction to maintain vehicle and business access. Environmental compliance includes a Streambed Alteration Agreement with the California Department of Fish and Wildlife and adherence to the Statewide NPDES General Construction Activity Permit. Construction is expected to span two seasons and may be implemented in two phases depending on funding. Critical scheduling constraints require that all in-channel and culvert work be performed during the dry season and outside the Clear Lake Hitch spawning season. The project is managed by Lake County, with oversight from the Lake County Department of Public Works and the Community Development Department.
