In an effort to shave approximately $13,000 off of its annual operating costs the Mackinac Bridge Authority and MDOT have put in place a plan to shut off the bridge's decorative lighting beginning at 1 a.m. In the past the decorative lights came on a sunset and shut off at sunrise. This way, folks can still see how pretty the bridge looks all lit up at night and the state can save money too. The roadway lights will remain on for safety, of course.
