Why this matters
The Mackinac Bridge is one of Michigan’s most critical transportation assets, and elevating it to statutory ‘key facility’ status raises the criminal-law stakes for trespass and interference with bridge operations. Enactment moves this from a proposed security tweak to operative law, aligning bridge protections with those already afforded other essential infrastructure.
