The Post-Independent reported Monday that the Colorado Department of Transportation expects to increase from 50 to 60 mph for most parts of the 14-mile canyon during good weather conditions.
Department officials said speed limits would drop to as low as needed when road conditions worsen or when construction and emergency closures occur.
Officials said the speed limit system would be the first of its kind installed in the state along with a dozen new signs, weather-monitoring stations and closed-circuit cameras. They said the partially-automated, partially-staffed technology is expected to be in place by November followed by a 90-day testing period.
