Traffic on Hamline didn't change. With and without the signs, speeds were 33 miles per hour northbound and 34 miles per hour southbound. It was a similar story on Thomas Avenue. Eastbound speeds averaged 32 miles per hour with and without the signs. The westbound traffic slowed only slightly when the art signs were posted from 34 to 33 miles per hour.
