Project Overview

Horry County Council passed a resolution of May 15, 2007, to enter into an intergovernmental agreement with the South Carolina Department of Transportation (SCDOT) to act as project/construction manager for those named state highway projects included on the road list. Those road projects include:

  1. a grade separated interchange at the intersection of US Highway 17 Bypass and SC Highway 707 at the backgate of the former Myrtle Beach Air Base;
  2. widen SC Highway 707 from Enterprise Road to the county line including intersection improvements at SC Highway 544;
  3. construction of the Aynor Overpass; and
  4. widen Glenns Bay Road to 3-lanes and construct a grade separated interchange at US Highway 17 Bypass.

As project/construction manager, the SCDOT will prepare for each project listed above a detailed scope of work, budget and schedule based upon three phases for each project:

  1. design, preliminary engineering and environmental work;
  2. right-of-way acquisition; and
  3. construction.
