SR 156 / SR 25 Turbo Roundabout Project

About the Project

Work is under way to build an innovative, multi-lane roundabout at the Highway 25/Highway 156 intersection north of Hollister. This is a critical safety project that will immediately reduce the number and severity of collisions at the intersection. Caltrans is planning to begin construction of the roundabout in June. The Measure G-funded project to widen Highway 25 (to be completed over the coming years) will also include a permanent interchange at this intersection to improve safety.
