Business Spur I-75 - Sault Ste. Marie

Business Spur I-75

The second Business Spur of I-75 runs 5.87 miles from Interstate 75 at Exit 392 north and east to the Sugar Island Ferry dock along the Saint Marys River. The route angles northeast from Three Mile Road along a commercialized stretch by Sault Sainte Marie Municipal Airport (ANJ) to Ashmun Street. Ashmun Street brings the route north to Downtown Sault St. Marie and East Portage Avenue. Crossing the Edison Power Canal from the business district, Business Spur I-75 continues along East Portage Avenue onto Riverside Drive before concluding at the ferry dock opposite 1 1/2 Mile Road on Sugar Island.

Interstate 75 north from Three Mile Road and the International Bridge opened to traffic in 1962. Business Spur I-75 was designated at this time with U.S. 2 along Three Mile Road to Mackinaw Trail and a new alignment northeast to former U.S. 2 (Ashmun Street) toward Downtown. U.S. 2 north from Three Mile Road shifted to the new freeway and toll bridge.1

Changes were made in 1981 when Business Spur I-75 was truncated from Portage Avenue south to Ashmun Street at Easterday Avenue. This lasted until 1984 when the 0.66 mile segment was restored to state control. Further additions to the route occurred in 1989 when 2.2 miles of Portage Avenue and Riverside Drive were added to the present eastern terminus.1
