Document Description
NOTE: FONSI/Notice of Availability NOTE: Joint Document consists of Mitigated Negative Declaration and Environmental Assessment. The California Department of Transportation proposes to relieve local and regional circulation problems and reduce existing and future congestion by improving the US 101/State Route 46 West interchange ramps, and relocating Theatre Drive to a new intersection with State Route 46 West, west of its current location. The interchange reconstruction would convert the existing compact diamond interchange signal-controlled ramp intersections into roundabouts. Adjacent frontage roads would be either redirected into the new roundabouts or relocated away from the interchange. The proposed project does not include any modifications to the US 101 through lanes. Improvements would be made to all four on- and off-ramps in the interchange to achieve the desired geometry and traffic operations.
