Dokken Engineering assisted with the damage assessment and completed the PS&E for emergency repairs to the Goodyear Bar Bridge. During the January 1997 New Year's flood on the North Fork of the Yuba River, two of the piers supporting the south approach were washed out resulting in the loss of three spans. Additional needed repairs included damage to lower chord of the main truss span, stabilization of the cylinder pier at the main span, and backfilling of the north abutment which was undercut and near failure.
Plans were prepared on a "fast track" schedule allowing construction of the replacement approach spans and other temporary repairs to be completed within six weeks. The bridge was re-opened to traffic on February 28, 1997, providing the people of Goodyear Bar with the access they needed.

Dokken Engineering also prepared the Permanent Restoration Report for the bridge project. This Report identified 3 alternatives for the permanent restoration of the bridge. Based upon the recommendations of the Report and public input, it was determined that the best alternative was to construct new reinforced concrete approach spans and relocate the existing main truss span to a new alignment immediately upstream of the existing bridge. This alternative, also involved raising the bridge to reduce the potential for future flood damage to the main truss span, and was approved for funding through the Federal ER Program and later approved for STIP matching funds and HBRR funding, as well. |
