Amenities taking form in Cimarron/I-25 work
One is the single-point urban interchange (SPUI) design for the on/off-ramps; the second is the quadrant/”shortcut” southeast of Cimarron (Highway 24) and Eighth Street; and the third is the last “half” of the new interstate bridge over Cimarron.
I-25 motorists will also be slowed through October by crews upgrading the overpass above Colorado Avenue, a Colorado Department of Transporta-tion (CDOT) press release states.
Meanwhile the overall schedule calls for completion by December. The contractor, Kraemer North America, started on the $113 million CDOT project in May 2015.
Here are capsules on the three new “experiences”:
A similar SPUI design exists at the Garden of the Gods/I-25 interchange. A difference at Cimarron/I-25 is the three left-turn lanes for vehicles heading toward the mountains from the northbound off-ramp .
The interchange's previous design - approved but unfunded as part of the 2005-2007 COSMIX I-25 widening project - had called for stoplights at the bottoms of the ramps, which would have meant two stoplights to get through instead of one.
The shortcut will be governed by a stoplight at Cimarron and another where it lines up with the access to the Colorado Place shopping center.
The bridge will handle three lanes of traffic each way, with a continuing ingress/egress lane on either side.
The first 80-foot width was completed last September.
The original bridge, built around 1960 for two lanes each way, was demolished last fall.
The 80-foot span is carrying all the I-25 traffic while the 71-footer is being readied.
