The movies aren’t the only place where you’ll see in 3D! Go check out Clark and Deming (about 2540 N Clark Street) in the Lincoln Park neighborhood to see a special pedestrian safety marking on the pavement. They were installed on October 18, 2010.
Who’s involved in the installation of these optical illusion zig-zag markings?
Chicago Department of Transportation (CDOT)
National Highway Traffic Safety Administration (NHTSA)
Western Michigan University (WMU)
