Document Description
Caltrans proposes to construct an undercrossing beneath Highway 101 south of the existing intersection, eliminating the need for motorists to make left turns across traffic on Highway 101. This would prevent future broadside and left-turn merge-related collisions at the intersection. The proposed undercrossing would consist of a 112-foot-long bridge on highway 101 matching the existing roadway geometry. Frontage roads would be constructed to connect the undercrossing with Wellsona Road on either side of Highway 101. Full closure of either Highway 101 or Wellsona Road is not anticipated for the project. The undercrossing would be constructed within the State right-of-way; however, the purchase of right-of-way would be required to construct the frontage roads that connect with Wellsona Road.
