Document Description
The Project proposes to build resiliency to the effects of projected 2130 sea level rise and stormwater overtopping onto SR 37 from Post Mile R11.2 to PM 13.8. The Project would replace the Novato Creek Bridge and construct a causeway at an elevation of 35 feet in 2 phases. The causeway would consist of 12-foot-wide lanes, a 22-foot-wide median with a 2-foot median barrier, two 10 foot-wide inside shoulders, two 12-foot-wide outside shoulders, two 2-foot-wide outside barriers, and a 14-foot-wide bicycle or pedestrian path with a 2-foot barrier, for a total roadway width of 114 feet. There would be no change to the long-term vehicular capacity on SR 37.
