The following is from the Decatur Police Department regarding all traffic information for tonight’s Callithumpian Parade:. As in the past each October, Decatur has its annual Callithumpian Parade. This year it is scheduled to be held on Monday, October 28 at 7:00 p.m. Prior to the 7:00 p.m. start of the parade, the parade route will be cleared of all traffic at 6:30 p.m. and will use the traffic detour on Jackson Street. In order to detour traffic from the parade route and downtown area, we will be using Jackson Street from the Bellmont High School intersection to the 5th Street intersection. We will be rerouting the large truck traffic along with all personal vehicle traffic on this street. This means that Jackson Street will become two-way traffic for the duration of the parade and it will become highly traveled.
