Designates the Mackinac Bridge as a key facility under Michigan law.

This bill amends Michigan's key facility law to include the Mackinac Bridge as a key facility. Key facilities are defined as structures or stations essential to public safety or economic stability, such as electric utility facilities, water treatment plants, and natural gas utility facilities. The bill specifies that individuals must not enter or remain on these facilities without authority, especially if they are completely enclosed and posted. The Mackinac Bridge is now included in this list, enhancing its protection under state law.
