MENUMENU

Marshland Road Roundabout at Mathews Drive – Hilton Head Island, SC

ICE was selected to provide design engineering services for intersection improvements at Marshland Road and Mathews Drive. A roundabout was designed to replace the current T-Intersection. ICE was challenged with providing plans that would tie into the superelevated, 2-lane Mathews Drive. The access was reduced on Mathews from two to one lane to allow for the construction of a single lane roundabout with a slip lane from Marshland Road. Care was taken when designing the roadway footprint and drainage to reduce the impact on the surrounding trees and minimize right-of-way acquisitions. Designs also include a reconfiguration of the sidewalk so that would it tie into the existing 10’ multi-use path.

This project won an ACEC-SC Engineering Excellence Award in 2016.
