Document Description
Caltrans replaced the Highway 128 Bridge over the Russian River in 2006 after one of the bridge piers failed. The bridge was closed from January 2006 through August 2006 during emergency bridge replacement/construction. In January 2010, Caltrans completed an emergency bank stabilization project along the upstream side of the western approach to the new bridge that consisted of placing approximately 500 cubic yards of rock slope protection (RSP) streambank during high winter flows. An additional 2,00 cubic yards of RSP was placed on the top of the eroding bank and against the bridge approach fill as an erodible buttress in the event that the 500 cubic yards that were placed in the river was insufficient to prevent further erosion.
The project involves specific actions necessary to prevent and mitigate an emergency situation that has a high probability of occurrence in the short-term.
