In 2010, this $6.88-million-dollar project won the Award for Excellence, American Concrete Pavement Association (Colorado-Wyoming Chapter), for Municipal Streets and Interchanges.
The new I-25 and High Plains Road Interchange seven miles south of Cheyenne showcases the first-ever roundabouts on the Wyoming highway system. The growing development southeast of Cheyenne prompted construction of the new interchange, which will relieve traffic at the College Drive Interchange to the north. Built in a standard diamond configuration, the interchange serves the Swan Ranch business park, the planned Southeast Wyoming Welcome Center, and new offices for the State Travel and Tourism Division. The east side of I-25 proved too close to the railroad for conventional access, so roundabouts for the intersection of the ramps with High Plains Road solved the right-of-way problem.
