In Design: Occohannock Creek Bridge Replacement (Route 178)

About the Project

The project is located on Route 178 (Shields Bridge Road) in the Hampton Roads District in Accomac Residency.  The bridge replacement project is located on Route 178 (Shields Bridge Road) from milepost 2.55 to MP 2.74.

The purpose of this project is to replace the bridge on Route 178 over Occohannock Creek in Accomack County (Federal ID 356, VA Structure Number 1007).  The current bridge is a steel span bridge with a stringer, multi-beam girder, which VDOT has determined to be structurally deficient and in need of replacement.  The existing bridge and approach roadway is a single lane facility classified as a Rural Major Collector. The bridge was built in 1933.  The existing bridge clearance is roughly 25 feet. The approaching roadway is approximately 21 feet wide.

The existing bridge will be demolished in a single phase of demolition with intent to close the bridge to traffic and re-route vehicles with a detour during construction.

Residents will be notified of potential traffic impacts and detours in advance of construction.

Benefits 

The purpose of the project is to replace the existing bridge over Occohannock Creek.

The project includes replacement of the bridge over Occohannock Creek and approach roadway tie-in work on either side. The current proposed bridge design provides more than 9-inches of additional clearance than the existing bridge and previous designs.

The project also includes installation of sheet pile walls adjacent to Occohannock Creek in order to contain approach fill material. Guardrail is also proposed on all bridge approaches and departures.
