Dokken Engineering completed Preliminary Assessment and Strategy Reports for 19 local agency bridges. Typical retrofits included seat extenders, restrainers at hinges, pipe restrainers at bents, rocker bearing replacement and abutment/column/ footing strengthening. Several of the bridges are located in areas with potential for liquefaction, which required three of the bridges to be replaced. The retrofit PS&E packages for 11 of the bridges were completed. Some of the bridges include:
- Empire Bridge (Santa Fe Avenue)/Tuolumne River: 495-foot long, 8-span haunched “T” beam girder bridge
|
- McHenry Avenue Bridge/Stanislaus River: 1,136-foot long, three concrete box girder spans at main channel and 32 concrete slab spans
- 9th Street (Old Highway 99)/ Tuolumne River: 2,027-foot long, 44 span steel girder bridge with composite concrete deck; this structure was slated for replacement and the PS&E was completed in 2003
- Crows Landing Road Bridge/San Joaquin River: 671-foot long, 18-span steel plate girder bridge with concrete deck
- Geer/Albers Road Bridge over the Tuolumne River: 656-foot long, 7-span concrete box girder bridge
