Document Description
Caltrans proposes to widen the intersection at Route 1 and Route 9 in the City of Santa Cruz, Santa Cruz County to accommodate additional vehicle turn lanes, bicycle lanes, and shoulders to improve traffic operations and better accommodate existing and projected traffic volumes. The primary improvements include: - On eastbound Route 1, add a left turn lane so two lanes turn onto northbound Route 9. - On northbound Route 9, add a concrete median, second traffic lane, shoulder, bike lane, and right-turn lane into the Tannery. - On southbound Route 9, add a shared through/left-turn lane and bike lane. - On northbound River Street, change the left-turn lane to a through/left-turn lane.
