Did you know that Colorado has a Scenic Bikeway Map? This map provides details of road shoulder width and expected traffic including truck traffic. This is a perfect tool for planning that next Colorado bike tour, whether it will just be a one day trip or weeks on end. The only thing really missing for the touring cyclist is campground information and their facilities but I'm sure that map exists as well.
