U.S. Bicycle Route 10 (USBR 10) is a United States Bicycle Route that is planned to follow U.S. Route 2 across the northern United States, beginning in Anacortes, Washington and ending in St. Ignace, Michigan. As of 2015, only 666 miles (1,072 km) of the planned corridor is designated, within the states of Washington, Idaho, and Michigan. The Washington segment was designated in May 2014 as the first national bicycle route in the state. The designation of the Michigan segment came shortly thereafter in November 2014, followed by an extension of the western segment into Idaho in May 2015.
