Airport Road Widening and Bridge Replacement Project at Sacramento River

Airport Road Widening and Bridge Replacement Project at Sacramento River

Replace the existing 1,285 foot long by 28 foot wide two-lane bridge on Airport Road at the Sacramento River with a new four-lane 1,430' by 69' wide bridge with bike lanes and sidewalks. New alignment will be immediately upstream of existing bridge at approximately the same elevation over the river. The existing bridge will remain in use during construction of the new bridge and will be removed when the new bridge is complete. The project will require the acquisition of approximately seven acres of new, permanent right-of-way from seven parcels. The approach roadway work will consist of widening the existing two-lane road to four lanes from the intersection of Airport Road and Riverside Avenue in the City of Anderson to the south, northerly to the intersection of Airport Road and Dersch Road. The southern approach will be approximately 900 feet long while the northern roadway will be 2,000 feet from the bridge to the Dersch Road intersection. Fills on the south approach will be around 18 feet at the abutment, while the north abutment approach could be up to five feet in places to smooth out a substandard vertical curve, with further cuts on the existing cut bank of the roadway of up to 10 feet. The majority of the roadway cut will be around two feet for the structural section. Numerous utilities are located throughout the project. Utility lines attached to the existing bridge will need to be relocated to the new bridge, including a high-pressure gas main. Trenching along the roadway for utilities will be up to five feet. Overhead utility pole relocation may require excavations up to 15 feet.
