Most of US 2 , along with US 23 in the Lower Peninsula , was designated the United Spanish War Veterans Memorial Highway in 1949 . To connect the gap in the routing where US 2 cuts through Wisconsin , M ‑ 95 and M ‑ 69 were used in place of US 2 between Iron Mountain and Crystal Falls . Signs marking the highway were not erected until 1968 when Governor George W. Romney had them installed .
