CDOT Celebrates Completion of State's Second Diverging Diamond Interchange

07-Jan-2016 to 12-Feb-2016

CDOT, High Performance Transportation Enterprise (HPTE), Plenary Roads Denver, Town of Superior, City of Louisville, and other project partners joined the US 36 Express Lanes Project team to officially open the state's second Diverging Diamond Interchange (DDI) at the McCaslin Boulevard bridge over US 36. A ribbon­-cutting ceremony was held January 7, to signify the official opening of the DDI bridge. 

The US 36 Express Lanes Project was built with the well ­defined strategy of moving traffic more efficiently. One innovation to help meet this goal was the addition of the DDI on the McCaslin Boulevard bridge in Louisville/Superior. The DDI is one of 34 DDIs in the country but only the second in the state of Colorado. The state's first DDI in Grand Junction opened in early 2014.

The bridge, which began construction last year, will still have some construction over the next few months to finish sidewalks, landscaping and striping, but drivers can experience the benefits now. There have been numerous small businesses and DBE/ESB certified firms that contributed to this milestone. Congratulations to the entire team!
