Abstract:
California Department of Transportation (Caltrans) determined that the Sonoma Creek Bridge was in need of seismic retrofit. Separate legislation through the State mandated a safety widening of the same structure due to it’s poor safety record and high traffic levels. Caltrans decided that the practical solution was to delay the retrofit design slightly and combine it with the safety widening project. The challenge was to properly seismically retrofit and widen the bridge and highway without impacting the sensitive, tidal marsh habitat.
