DOUGLAS COUNTY — Three structures are scheduled to be completed this month as part of CDOT's I-25 South Gap project.
The Greenland Road and I-25 interchange is expected to open the morning of Dec. 22 and two new wildlife underpasses have already been completed.
According to CDOT, crews have been working since June 2019 to transform the single-lane box culvert (circa 1948) into a full two-lane underpass while also flattening curves along I-25 approaching the interchange and widening the interstate. With the bridge complete, traffic will be shifted into its final alignment on I-25.
The wildlife underpasses are located just south of the Greenland Road interchange and just north of the County Line Road bridge. Each wildlife underpass is 100 feet wide and 18 feet tall. A total of four new underpasses along this wildlife corridor are expected to result in a 90% decline in wildlife versus vehicle collisions, CDOT said.
