Medical District Drainage Tunnel Extension at Ehrhardt Street

  1. Project Overview

About the Project

The Charleston Medical District is home to three major medical centers: MUSC, VA, and Roper Hospital. Together, this includes the premier medical university of the region, the region’s only Children’s Hospital, and the Veterans Administration.Ehrhardt 2

The Medical District is increasingly threatened by repetitive flooding. Major storm events hit Charleston multiple times every year affecting access to essential medical care, including emergency vehicle access to the Medical District. When operations are interrupted, it has a dramatic impact on the public health and safety for employees, patients, visitors, and residents of the area. Without intervention, the delivery of healthcare itself is at risk.

The Ehrhardt Project will construct a deep tunnel extension and drop shaft to drain the street level stormwater collection system into the deep tunnel and pump systems of the US-17/Spring-Fishburne Project. The City is currently constructing the US-17/Spring-Fishburne project and is expecting to begin the Medical District Drainage Tunnel Extension at Ehrhardt Street project in early 2022.
