Konocti Corridor (Formerly Lake 29 Improvement)

The California Department of Transportation (Caltrans), the Lake County Area Planning Council (LAPC), and the Federal Highway Administration (FHWA) propose to widen an eight-mile segment of State Route 29 in Lake County to a four-lane expressway with access control. This project is located between the communities of Lower Lake and Kelseyville. In addition to the "No-Build" Alternative, four alternatives are under consideration at this time.
