Olancha Cartago 4 Lane Project
The California Department of Transportation (Caltrans), as CEQA lead agency, and the Federal Highway Administration (FHWA), as NEPA lead agency with the support of Inyo County Local Transportation Commission will convert approximately 12.6 miles of the existing U.S. Highway from a two-lane conventional highway into a four-lane expressway from post mile 29.2 to post mile 41.8 in Inyo County.
The controlled-access four-lane divided expressway will pass west of Olancha and the Los Angeles Aqueduct. Once the alignment crosses Olancha Creek, the project will cross the Los Angeles Aqueduct and continue north through Cartago along the existing highway to meet up with the four-lane section of U.S. Highway 395 to the north of Cartago. The northbound and southbound lanes would be separated by a 100-foot-wide unpaved median.

The Final Environmental Document was signed in May 2017. The selected alternative, a combination of Alternative 4 in the south and Alternative 3 in the north, will be an expressway with access control. This alternative reduces environmental impacts, residence relocations, and direct impacts to businesses while increasing safety and meeting the purpose and need of the project. A route adoption will be required for the expressway alignment. Furthermore, Caltrans intends to relinquish a portion of the existing two-lane highway to Inyo County.
Why this project is needed
US 395 is a Priority Interregional Highway in the Caltrans Interregional Transportation Strategic Plan, part of the National Network of truck routes, and included in the Caltrans Highway Freight Network. The highway is vital to the economy of the Eastern Sierra region and is one of five major recreational corridors identified for Southern California. The highway has recurrent congestion and the fatal accident rate is higher than the statewide average for a similar facility.
This project will address roadway safety, provide for continuity of the US 395 corridor, meet present and future vehicular and goods movement traffic demands, and bring the highway up to current design standards. It will include Complete Streets elements, such as, new shoulders, a new non-motorized multi-use undercrossing, Class III Bike Route, bus turnout, and potential intersection improvements that would benefit pedestrian and bicycle mobility.
Funding and Partnership
The project is expected to be jointly funded by Inyo and Mono Counties’ Local Transportation Commissions and Kern Council of Governments and Caltrans with State Transportation Improvement Program (STIP) funds.

The California Department of Transportation (Caltrans), as CEQA lead agency, and the Federal Highway Administration (FHWA), as NEPA lead agency, propose to convert approximately 12.6 miles of the existing U.S. Highway from a two-lane conventional highway into a four-lane expressway or partial conventional four-lane highway from post mile 29.2 to post mile 41.8 in Inyo County. The project proposes six alternatives with varying amounts of construction on new alignments.
The Draft Environmental Impact Report/Environmental Assessment with Section 4(f) Evaluation was circulated from August 12, 2015 through October 10, 2015 and a Public Hearing was held on September 23, 2015 in Olancha. All comments received during circulation have been addressed in the Final Environmental Impact Report/Environmental Assessment with Finding of No Significant Impact and Section 4(f) Evaluation which can be found on this webpage and a the following location.
