Columbus County getting new interchange and bridge By WECT Staff | May 4, 2021 at 9:26 AM EDT - Updated May 4 at 10:14 AM BOARDMAN, N.C. (WECT) - Another interchange and bridge will be constructed on U.S 74 in western Columbus County. BMCO Construction Inc. of Lumberton will construct the improvements where Old Boardman Road/Macedonia Church Road intersect U.S. 74. Drivers from either side currently must stop and look for a safe opening before pulling out onto the four-lane highway. The overpass and ramps will be built on the east side of the current intersection, which will remain open during construction. When the interchange is completed, the route will be realigned to the new on/off ramps, which will have roundabouts.
