Document Description
The proposed Project will replace the existing Robinson Creek Bridge on Lambert Lane, approximately 400 feet west of State Route (SR) 128. The existing structure is 32 feet long and 26 feet wide reinforced concrete bridge with closed strutted abutments founded on spread footings on erodible alluvial material. This bridge has a history of scour issues and a scour hole that has undermined the integrity of the easterly bridge abutment. The existing bridge has been closed and a temporary bridge has been installed until it can be permanently replaced. There are deficiencies in the bridge width, superstructure and substructure conditions. The replacement bridge will have 9-foot lanes and 5-foot shoulders in each direction resulting in a wider structure which meets safety standards. In addition to the bridge replacement, portions of the stream channel upstream and downstream of the bridge will be stabilized according to the Robinson Creek Channel Design for the Lambert Lane Bridge Replacement Project.
