Environmental sustainability and land stewardship are challenging but laudable constraints for all infrastructure development in the United States. Our nation's prevalent energy concerns, which include the desire for energy independence coupled with a growing population requiring additional energy capacity, constrain energy available to repair and build new infrastructure. The Colorado Department of Transportation (CDOT) has identified the maintenance and improvement of roadways in addition to increased construction of local road systems as strategic goals in the statewide transportation plan (CDOT 2008). These goals will support an overarching objective in Colorado to enhance transportation safety while meeting future needs of increased transportation capacity.
