ADVISORY – Sault Ste. Marie International Bridge advising essential travel only

Update:  I-75 reopened. 5:20pm.

Original Travel Advisory:

The Sault Ste. Marie International Bridge remains open traffic this morning but, consistent with all other travel advisories, the International Bridge Administration (IBA) is advising drivers use the bridge only for essential travel.

IBA Administration Office services are closed and will reopen at 7 a.m. Tuesday.

Southbound I-75 is closed just south of the bridge at the Easterday exit. Multiple roadways remain closed in the Upper Peninsula this morning, including portions of I-75, US-2 M-26, M-28 and M-129.   Reopening some of these roadways after severe blowing and drifting may take several more hours.

IBA reminds motorists they should never bypass a road closure barrier, even if crews are plowing beyond or around the barrier. When you enter a closed section of roadway, you inhibit the ability of crews to clear the roads and pose a real danger to plow operators and yourself.

The IBA will post updates on its website,, and its Twitter feed, @SaultBridge.
