The purpose of the project was to replace the existing bridge and improve roadway approaches in order to: enhance safety; carry both legal and permit loads; provide a transportation facility consistent with local, regional, and statewide plans, and Caltrans standards. The proposed Build Alternative replaced the existing bridge with a new bridge meeting current design standards. Rehabilitation of the approach roadways was also made on both sides of the bridge. Access to buildings at the project site was maintained throughout construction. The bridge was removed and constructed in stages to accommodate two lanes of traffic continuously. Pedestrians were accommodated with a temporary crosswalk. Temporary falsework was used to support the new bridge structure during construction. Water within the creek was temporarily channelized using water diversion methods.
The Badger Street Bridge was constructed in 1960 and was also classified as “structurally deficient”. The existing bridge had five spans supported by three sets of piers made up of reinforced concrete located on reinforced concrete spread footings. The bridge was inundated during storm events and overtoped by up to six feet during a 100 year flood. During heavy storm events the bridge was closed to through traffic by a chain-link fence gate. The City secured HBP funding through Caltrans to replace the bridge. The proposed project involved removing and replacing the existing bridge with a raised bridge (approximately ten feet higher) and roadway profile at the crossing of Sutter Creek. The lower five-span bridge was replaced with a higher profile two-span bridge capable of passing 100-year flood flows without overtopping. The road within the project area was closed during the project. Water within the creek was temporarily channelized using water diversion methods.
