I live in the Monument area, and I commute to the Denver Tech Center each day to work here at KYGO. So, twice a day since January, I encountered bridge construction on I-25 on my way to and from work. I always assumed the bridge was for cars, but it’s actually not for humans at all…
The bridge I speak of is the “Greenland Wildlife Overpass” in Douglas County, and it’s essentially a bridge over the highway for animals. The goal is to protect wildlife from being hit by vehicles.
These bridges are becoming more popular in Colorado, but this particular bridge is the biggest one in the world! It covers six lanes of I-25 and creates 39,000 acres of land together. The overpass is 204 feet wide and was $15 million.
The overpass is a critical component of the overall wildlife crossing system that is expected to reduce wildlife-vehicle crashes along this stretch of I-25 by 90 percent.
Construction of the overpass, just south of Larkspur, is now complete, according to the Colorado Department of Transportation (CDOT).
