Roberts Road Diverging Diamond Interchange (DDI)
A congested interchange in the midst of a heavily traveled industrial, commercial, and residential area has received a major overhaul. The previous diamond interchange at I-270 & Roberts Road in Columbus, Ohio has been transformed into a Diverging Diamond Interchange (DDI) – an emerging and cost effective roadway solution designed to improve safety, reduce crashes, and ease congestion. It is the first DDI constructed in the state of Ohio and was the 23rd in the United States.
The previous diamond interchange diamond interchange had geometric design deficiencies and a high frequency of congestion-related crashes. The former interchange also couldn’t handle the high volume of traffic that travels through it – including a large amount of trucks that drive area commerce.
Some key components of the I-270/Roberts Road DDI include:
This presentation will discuss the intricacies of the planning effort, the key aspects of the design, and lessons learned during both design and construction. As the Project Manager of the design team, Mr. Toombs will provide insight about design and construction, including lessons learned during various points in the process.
