NCDOT selected Vaughn & Melton as one of the regional firms to provide complete design support services for all the divisions in the western region.  The services Vaughn & Melton was required to provide included Planning, Location & Surveys,

One of these projects included design of a traffic circle (roundabout) at the east sector of the interchange at I-26 and NC108 near Columbus.  NCDOT had already built a traffic circle (see figure 1) at the west sector of this interchange, and after realizing the benefits to this heavily congested area employed Vaughn & Melton to

survey the existing conditions and design a traffic circle for the east sector that duplicated the new traffic circle in operation of the west sector.  (See figure 2)  This design also involved designing an 8’ x 8’ box culvert extension needed for the additional fill slopes.
