US 76 WB Over Wateree River
Westbound US 76 serves as one of the primary evacuation routes from the Pee Dee region. The 2,300’ US 76 westbound bridge over Wateree River is structurally deficient and does not meet current standards for shoulder width. 2,196 square miles of the 5,485-square-mile watershed are located within the state boundaries and drain approximately 7% of South Carolina to the site. Davis & Floyd is providing project management, roadway design, hydrologic and hydraulic design (including 2D modeling), surveying, environmental services, permitting, and QA/QC design services for bridge and roadway designs.
Solutions
The bridge likely will be replaced along the existing alignment to avoid impacting the existing boat ramp to the south and designated mitigation area to the north. Replacement will require transition of westbound traffic to the eastbound roadway and bridge during construction. The Wateree River will require 2D hydraulic modeling and detailed scour analysis. Approximately 500’-deep soil borings also will be performed on this project.
