Mokelumne River Bridge Upgrade

Project Description

The proposed project is located on State Route (SR) 49 at the Mokelumne River Bridge (Br. No. 26-0012) at the Calaveras/Amador County line. The preferred alternative’s scope of work is to replace the rails and widen the bridge to include 4-foot shoulders. The roadway approach shoulders will also be widened on both ends of the bridge for approximately 75 feet to match the widened structure and the adjacent roadway segments.


Project Benefits


The purpose of this project is to upgrade the bridge rails to meet current crash safety standards and to widen the bridge to enhance the mobility of pedestrian and bicycle traffic.


The Structure Replacement and Improvement Needs Report (STRAIN), prepared by the Office of Structures Maintenance and Investigations, has identified the need to upgrade the nonstandard concrete baluster bridge rails (Attachment E). Additionally, the existing shoulder width on the bridge does not meet the needs of bicycle and pedestrian traffic.


Funding Source
