Caltrans is set to modify the intersection of Highway 1 and Santa Lucia Canyon Road near Lompoc as part of a three-phase plan to enhance safety.

The work will permanently eliminate left-turn maneuvers from Santa Lucia Canyon Road onto northbound Highway 1 and right-turn maneuvers from Santa Lucia Canyon Road onto southbound Highway 1 toward Vandenberg Space Force Base.

The changes address a history of collisions at the intersection, including a November 2024 multi-vehicle crash that injured six, and a December 2024 wet-weather collision that claimed the life of 19-year-old Santa Maria resident Asher Linden Tenud and critically injured Krissy Partlow, of Lompoc.

The project, contracted to Brough Construction, Inc. of Arroyo Grande, will begin with temporary ramp closures on Tuesday, Aug.
