Document Description
The proposed project would demolish the current West Branch Cherokee Creek bridge (Bridge #30-0036, Cherokee Bridge) and replace ii with a new structure. The existing bridge is more than 80 years old, with a soffil elevation of 1,422.7 feet above mean sea level. The guardrails do not meet current Callrans standards and, although the structure currently has 12-foot-wide lanes, there are no shoulders along this area.
The proposed bridge design would increase the soffit elevation by 4 feet (to 1,426.7 feet above mean sea level). This would 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 would 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.
