I-70 Exit 26 Interchange Traffic to Switch to Diverging Diamond Configuration

I-70 Exit 26 Interchange Traffic to Switch to
Diverging Diamond Configuration
Traffic switch scheduled for Tuesday night, followed by winter suspension of work on Monday, December 23
GRAND JUNCTION— The Colorado Department of Transportation (CDOT) has been constructing the state’s first Diverging Diamond Interchange (DDI) at the I-70 Exit 26 interchange since early July. Work has now progressed to the point where traffic will be placed into the new DDI sometime on Tuesday evening, December 17th.
Because DDIs are so new, most drivers will notice the significantly different traffic pattern through the interchange come Wednesday morning. When driving a DDI, motorists proceed through a traffic signal at the entrance to the interchange, and simply follow their lane to the opposite side of the roadway. Motorists needing to access I-70 will turn left at the on-ramp without having to stop again or wait for oncoming traffic to pass. Through traffic proceeds to a second traffic signal and follows their lane back to the right side of the road.

TRAFFIC IMPACTS: .The DDI configuration will be in place for morning traffic on Wednesday, December 17th One lane of traffic will be opened in each direction for about a week until all work in the travel lanes is completed. This work is scheduled to be completed by Monday, December 23rd. At that point all four lanes on US 6 & 50 will be opened and the project will be shut down for the winter. Work on the project will begin again when the snow is gone and the ground has thawed, likely in March or April. However, work could begin again before March if the weather turns better before then. When the project starts up again, work on the remaining off-line improvements such as landscaping, sidewalks and revegetation, will be done. This work will take 3 – 4 weeks to complete and will not impact traffic in the travel lanes. However, some shoulder closures will be required. The speed limit will remain reduced to 35 mph until construction is complete.

During the time between the traffic switch next Tuesday and the winter shutdown on Monday, December 23rd, CDOT and the contractor are asking the public to be aware of construction workers and activities and to drive cautiously through the construction zone.
