Marsh Creek Road Shoulder Widening

Document Description: The purpose of this project is to improve a 2,900 ft. section of Marsh Creek Road 100 ft. west of Round Valley Park entrance to Lydia Lane. The improvements are intended to develop a recovery area which will assist drivers when their vehicles veer out of the travel lane, and increase overall road safety by widening the travel lanes and improving driver sight distance by altering the road's vertical and horizontal curves to meet current design standards.
