Design/Build DDI in North Carolina

Updated: May 17, 2011

Abstract: I-485 will be completed as a beltway around Charlotte with a couple of new interchanges. The interchange at this location will be a DDI. Originally planned for a 10 lane SPUI bridge with failing LOS, I was able to convert this to a 7 lane DDI with LOS D or better for all movements in the design year.
