Document Description
The purpose of the Project is to replace six corrugated metal pipe culverts with ten precast box culverts. The existing culverts are deteriorating and have compromised functionality. Replacement of the culverts with a larger size system will increase hydraulic capacity, reduce the potential for waters to flood over the highway, and restore stream flow rates to levels similar to pre-culvert conditions.
