Konocti Corridor (Formerly Lake 29 Improvement)

As of June 2023, the first, three-mile section known (segment 2C) is complete.

This project is a cooperative effort with the California Department of Transportation (Caltrans), the Lake County Area Planning Council (LAPC), and the Federal Highway Administration (FHWA). Located between the communities of Lower Lake and Kelseyville in Lake County, the $85 million first phase of the project widened a three-mile segment of Route 29 to a four-lane expressway to improve safety.

A hybrid satellite and road map shows the 2a segment of the Konocti Corridor Improvement Project. The map shows the segment beginning at postmile 23.6 and end at postmile 26.9.  A hybrid satellite and road map shows the 2b segment of the Konocti Corridor Improvement Project. The map shows the segment beginning at postmile 25.7 and end at postmile 29.1.

In total, the project will widen an eight-mile section of Route 29 and is separated into three different segments. Along with the newly completed 2C segment, the other two portions, segment 2A and 2B, are to the east of 2C, and the partners are working to secure funding to complete the project.
