PROJECT OVERVIEW

The Santa Barbara segment will start between Olive Mill and Hermosillo Roads in late summer 2024. Crews will begin by strengthening the shoulders and median areas to prepare for upcoming lane shifts. In the fall, crews will work on new northbound lanes and ramps.

​Measure A and Senate Bill 1 are funding the southern portion of the Santa Barbara segment. The southern section includes new carpool lanes, updated safety barriers and freeway lanes, sound walls, and on- and off-ramps. The project team is applying for funds for the North segment that includes the redesign of the Cabrillo Boulevard Intersection with new bridges, lanes, on- and off-ramps, and local street improvements.

The timeline is a reference tool to show planned improvements and key closures. The timing may change to accommodate modifications from the contractor, weather delays, and to improve construction.

Construction is scheduled from late summer 2024 through 2026. Highway 101 will have 2 lanes open in each direction during daytime construction. There will be nighttime lane and ramp closures with signed detours as needed.
