McCaslin Blvd. Diverging Diamond Interchange Grand Opening

The Colorado Department of Transportation (CDOT), High Performance Transportation Enterprise (HPTE), Plenary Roads Denver, Town of Superior and City of Louisville premiered the state’s second Diverging Diamond Interchange (DDI) at the McCaslin Boulevard bridge over US 36 on Thursday, Jan. 7. The event featured a formal ribbon-cutting on top of the bridge, followed by a speaking program at the local Cinebarre movie theater. CIG was able to play off of the décor and theme of the theater throughout the event – from the invitation, which resembled a vintage move poster, to the popcorn snacks and commemorative soda cup giveaways.

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 DDI helps move traffic across the bridge more efficiently by crossing traffic to the opposite side of the road across the interchange so vehicles have unimpeded movement onto the highway ramps. In addition, DDIs increase left-turn capacity, accommodate more traffic with fewer lanes and reduce delays by using a two-phase signal as opposed to traditional traffic signals.
