The purpose of the project was to resurface the existing gravel road and replace the existing Ekola Bridge in preparation for anticipated heavy construction traffic during the construction of the Aeolus Substation. Inberg-Miller Engineers teamed with Oftedal Construction under a design-built contract to provide professional engineering and land surveying services.

The CCR 121/Ekola Bridge project consisted of the construction of a new bridge crossing the Medicine Bow River located approximately 200 feet southwest of the existing Ekola Bridge. Due to the location of the bridge replacement, approximately 0.76 miles of County Road 121 was realigned to match the location of the new bridge. The project also consisted of resurfacing approximately 9.45 miles of gravel roadway along Carbon County Road 121 from the intersection of US Highway 30 to a point approximately 900 feet north of the Medicine Bow River bridge crossing.
