Home » Guides » Michigan » Business Loop I-94 - Port Huron

The skyline of Sarnia, Ontario faces Port Huron in this view from Vantage Point, three blocks east of Business Loops I-69 & 94 (Military Street) in Port Huron. Photo taken November 6, 2011.

The easternmost business loop for Interstate 94 replaced M-25 northeast from Exit 266 to Exit 275. Designated by 1987 as M-25 was decommissioned,1 the route follows Gratiot Boulevard through Marysville and the north end of M-29 (Bushna Highway). Northward from Bushna Highway, Gratiot Boulevard parallels the St. Clair River to a couplet at South Park in Port Huron. Military Park carries the eastbound route while Electric Avenue accommodates westbound drivers.

The two one-way streets combine and carry Military Street northward to the couplet of Griswold Street (west) and Oak Street (east), the route of Business Loop I-69 leading to the west split of Interstates 69 and 94. Business Loop I-69 & 94 combine northward along Military (Main) Street across the Black River onto Huron Avenue through Downtown Port Huron. Pine Grove Avenue bends westward from Huron Avenue as the final leg of both Business Loops to their end at the Blue Water Bridge to Sarnia, Ontario.

A $90-million reconstruction project involving 2.2 miles of Interstates 69 and 94 east from Lapeer Road to the Bluewater Bridge included the addition of a new northbound off-ramp to Pine Grove Avenue (Business Loops I-69 & 94). The new ramp departs from the expanded Black River Bridge to replace a left-hand ramp onto a connector leading north to Pine Grove Avenue near Garfield Street. Work also involved the demolition of homes along Scott Avenue and the removal of Mansfield Street west of Pine Grove Avenue. Construction was undertaken between March 2011 and October 19, 2012.2
