The interchange bridge, two roundabouts, and ramps took 46 days to complete and only one short detour remains on the schedule. The $6.1 million Interchange widens and replaces the bridge deck over I-25. Roundabouts on both ends enhance continuous traffic flow, allowing motorists to take advantage of natural gaps between vehicles and merge rather than make a complete stop. The aesthetic improvements include decorative treatments and landscaping that complement those of other new projects in the area.
