The tunnel will house a replacement segment for the Enbridge Line 5 light oil and natural gas liquids (NGL) 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.
