Design/Build DDI in North Carolina
Details    Edit
Updated: May 18, 2011
 Freeway Interchanges  Diverging Diamond Interchanges  Existing
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.

Likely First DDI Considered in the US
Details    Edit
Updated: May 18, 2011
 Freeway Interchanges  Diverging Diamond Interchanges  Conceptual Planning
Abstract: New interchanges were considered at this location in 2005, with the widening of both Hanover Road and MD 295. The DDI was not selected as the chosen alternative because state officials did not want the first DDI in Maryland to go in a location where there would be a lot of unfamiliar drivers. This new interchange is planned to be the entrance to the rental car facility for BWI Airport.
