Toledo, Ohio — The Ohio Department of Transportation (ODOT) awarded a design contract for a new Diverging Diamond Interchange (DDI) in Toledo to Arcadis. The $26.3 million DDI project is expected to relieve traffic congestion and reduce accidents in the Toledo area.

Increased transportation demands in Northwest Ohio have presented challenges for state and local officials who have worked to find a solution for the safe and efficient movement of people, goods and materials across the state.  ODOT selected the DDI as the best option for both safety and traffic flow.

The Diverging Diamond Interchange was listed by Popular Science magazine as one of the best engineering innovations in 2009. The key design features of the DDI are crossovers on either side of the interchange which result in fewer conflict points and improved operations. The new DDI will be one of only three in Ohio.

Wassim Selman, infrastructure president for Arcadis in North America, stated: “We are eager to partner with the Ohio Department of Transportation once again in Toledo to implement an innovative traffic solution. This design will improve access to existing and future development while improving safety on Ohio interstates.”

Arcadis will serve as prime consultant for the contract that includes preliminary engineering, environmental clearance and final design.
