M-123 is a state trunkline highway in the eastern Upper Peninsula that runs north from the St. Ignace area. It is one of only a few highways in Michigan that curve around and form a U-shape. In fact, M-123 has three intersections with only two state trunklines; it meets M-28 twice as a result of its U-shaped routing. M-123 also has a rare signed concurrency with a County-Designated Highway in Michigan; in Trout Lake, there is an overlap between H-40 and M-123. All of M-123 north of M-28 is a Scenic Heritage Route within the Michigan Heritage Route system. That section runs along Whitefish Bay and through the Tahquamenon Falls State Park, providing access to the most voluminous vertical waterfall east of the Mississippi River after Niagara Falls. The road also runs along the Tahquamenon River before turning south to its terminus in Newberry. The highway was first designated before 1936 along a section of its current routing. Sections added since then encompass segments formerly belonging to US Highway 2 (US 2) and M-48. The last changes came to the highway in 1962 and 1963, when the northern end was extended and the southern end was truncated slightly. (more...)
