At its discretion, the department may inventory and evaluate designated Iowa Byways or portions of byways to determine their continued eligibility for the program. The department reserves the right to remove a route or portion of a route from the program if the route no longer meets the designating criteria or if the route signage has not been maintained. The department may modify an existing route if an alternative route would better benefit the traveling public in cases of poor road conditions, closures or changes in available amenities.
