CDOT Building First Diverging Diamond Interchange in Colorado
The Colorado Dept. of Transportation and the city of Grand Junction are partnering to bring the state its first diverging diamond interchange. The DDI is an innovative interchange design that improves efficiency by eliminating some of the wait time for left-hand turns.
The project represents a partnership between CDOT and the city of Grand Junction to improve safety and traffic flow on I-70 at Exit 26 (U.S. 6 & 50). The contractor began mobilizing equipment to the area on July 8. The I-70 DDI is the first in the state—some 15-plus DDIs have been built in the U.S., the first being in Springfield, Mo. The I-70 DDI project, which will continue through November, was designed by the city of Grand Junction and is being constructed by CDOT.
