Thomas & Hutton provided a traffic impact study for the relocation of the East Cooper Regional Medical Center. The study evaluated various intersection configurations and access scenarios to determine an optimal roadway plan for the hospital campus. At one of the access points, a roundabout was compared to a standard signalized intersection to determine the best operational plan. As a result of the study and associated traffic analysis, a roundabout was recommended. Thomas & Hutton provided surveying, platting, traffic studies, roadway design, drainage design, permitting assistance, and construction administration.
In coordination with the Town and SCDOT, Thomas & Hutton prepared the concept development, drainage study/report, preliminary plans, right-of-way plans, and final construction plans for the Mathis Ferry Road/Hospital Drive roundabout. Through careful coordination with the site contractors and the owner during the construction phase, Thomas & Hutton assisted in identifying value engineered solutions that contributed to an overall cost-savings of approximately 15-percent of the original construction budget. Additionally, we provided expeditious response throughout the construction phase that aided the site contractor in completing the construction on schedule.
The new roundabout created a new entry point for the hospital and tied into an existing subdivision road. This included the realignment of an existing road and the extension of the same road to connect Mathis Ferry Road to Bowman Road, both roads maintained by the SCDOT. In addition, the alignment and intersection of the southern portion of the road was coordinated with the Town of Mount Pleasant, Charleston County, and the SCDOT in conjunction with their widening of Bowman Road and the adjacent Highway 17. The project included the construction of an 8-foot wide shared-use sidewalk, along with street lamps to facilitate pedestrian traffic along the route.
