Siskiyou Co. DPW - Canyon Creek Bridge Replacement
Document Type
NOE - Notice of Exemption
Document Description
The project includes replacement of the existing steel truss bridge with a rail car bridge. The existing steel truss bridge rests on deteriorated timber abutments and associated wingwalls. The timber abutments and wingwalls will be removed and new abutments will be constructed in the same location using rock gabion baskets. Concrete caps will be poured on top of the gabion baskets to support the new railcar bridge. Rock slope protection (RSP) will be added around the gabion baskets to protect the new bridge abutments. The new abutments and RSP have been designed so they will not result in any additional areas of permanent impact to the streambank. The project includes installation of a temporary bridge over Canyon Creek approximately 70 feet downstrea of Boulder Creek Road in order to provide a temporary crossing and access to private property.
