Implementing Innovative Interchanges: Highlights and Lessons Learned about Diverging Diamond Interchanges
A Diverging Diamond Interchange (DDI) is an innovative interchange design that has proven to be a sound transportation solution for many municipalities. In three states, B&N has been the first engineering firm to design or help implement a DDI for our clients.
This session will highlight B&N’s experience and lessons learned during stakeholder outreach and education, the design and construction process, and implementation of Diverging Diamond Interchanges. The 20-minute presentation will be followed by a Q&A session with a panel of experts, including Brian Toombs. The panel will discuss additional geometric roadway designs, such as roundabouts and Complete Streets.
