Mackinac Straits Corridor Authority (MSCA)

The Mackinac Straits Corridor Authority (MSCA) is responsible for overseeing construction and operation of a tunnel in bedrock beneath the waters of the Straits of Mackinac. The tunnel will house a replacement segment for the Line 5 petroleum pipelines that currently sit on the bottom of the Straits and will accommodate other utilities to improve infrastructure connections between the peninsulas.

MSCA will own the tunnel after its construction and provide independent oversight throughout its life.
