The TH 61 North Shore Scenic Highway is a 150-mile coastal interregional highway corridor that links northeastern Minnesota with the rest of the state, nation, and Canada. The design and construction of the TH 61 realignment also involved mining a tunnel through Silver Creek Cliff to provide a safe, cost-effective, and state-of-the-art system to replace a dangerous steep and narrow two-lane roadway on the side of the cliff.
