West Branch Cherokee Creek Bridge
The proposed project will demolish the current West Branch Cherokee Creek Bridge (Bridge #30-0036, Cherokee Bridge) and replace it with a new structure. The existing bridge is more than 80 years old, with a soffit elevation of 1,422.7 feet above mean sea level. The bridge structure is currently capable of accommodating 800 cubic feet per second of water flow. The guardrails do not meet current Caltrans standards and, although the structure currently has 12-foot-wide lanes, there are no shoulders along this area.
The proposed bridge design will increase the soffit elevation by 4 feet (to 1,426.7 feet above mean sea level). This will require that the bridge span (length) increase to 31 feet and that the roadway on either end be elevated to match the bridge elevation. The new structure will pass 1,800 cubic feet per second of water flow and provide 2 feet of freeboard (distance from water surface to bottom of bridge soffit), allowing water-borne debris to pass through and prevent the bridge from failing.
