Michigan's signature landmark, The Big Mac Bridge, will turn blue tonight.

Today is Global Autism Awareness Day so Autism advocates are lighting the Mackinac Bridge blue to bring more awareness to the disorder.

It's being called "Light it Blue Michigan," and it's the first time the state is participating in this international event, hoping to bring light to the 15,000 Michigan children who have autism.  Michigan is fourth in the number of children with autism in the U.S.

Michigan Lt. Governor Brian Calley, who has a daughter with autism, will be the featured speaker at the ceremony. He has been pushing to expand health insurance coverage for autistic children, and Governor Rick Snyder is expected to sign a bill later this month to do just that.

The bridge project is being paid for by the non-profit Corner Pieces. MDOT will "Light it Blue" at sundown, and the bridge will stay blue the entire month of April.
