Cottonwood Creek Bridge Replacement
Project Description (06-0V120)
The project would replace the two existing mainline bridges over Cottonwood Creek on State Route 99 in Madera County and one on the northbound off-ramp to Avenue 12/Road 29 from State Route 99. The Build Alternative offers two bridge construction type options.
Project Benefits
Purpose
The purpose of the project is to replace three aging bridges on State Route 99 over Cottonwood Creek in Madera County.
Need
A Structure Maintenance and Investigations Bridge Maintenance Strategy Meeting held on September 1, 2015 recommended replacing the concrete bridges because of steel corrosion, deck deterioration, and superstructure and substructure distress related to chloride intrusion.
The bridges have a long history of deck and soffit deterioration. According to a 2011 test on the bridge, water and salt have reached levels that corrode the steel in the reinforced concrete of the bridge. The mainline bridge piles on the northbound and southbound State Route 99 bridges are exposed, as shown in the figures below.
In addition, the asphalt overlay on the State Route 99 bridges is continually deteriorating, resulting in repeated emergency repair projects. The northbound and southbound State Route 99 bridges have had spot failures in the decks that have required patching. The project would repair the decks and the pavement on the decks of the bridges, which would eliminate costly ongoing maintenance projects. The soffits (areas between the support beams of the bridge) of the two structures show cracking, salt residue, spots of distressed concrete and evidence of full-depth repairs.
The Structure Replacement and Improvement Needs Report also identified the need to upgrade the non-standard bridge rails.
