Iron County Road Commission Imposes County-Wide Spring Road Restrictions Starting March 5

Spring frost has arrived, and with it, the Iron County Road Commission has imposed county-wide seasonal road restrictions that took effect March 5, 2026, covering every road in the county around the clock until further notice.

The restrictions, classified as spring seasonal/frost road restrictions, apply 24 hours a day, seven days a week with no defined end date. Last year, the commission lifted equivalent restrictions at 6:00 a.m. on Wednesday, May 14, 2025, offering a rough historical reference point for how long the current restrictions could remain in place.

The scale of what these restrictions govern is considerable. The Iron County Road Commission maintains 224 MDOT highway miles along with 633 primary and local miles of road, a combined network that spans the county's forests, townships, and corridors connecting communities throughout Iron County.

Spring road restrictions are a recurring feature of Upper Peninsula winters giving way to thaw season. As frozen ground softens, roads become vulnerable to damage from heavy loads, and weight-bearing restrictions protect the pavement and gravel surfaces from structural harm during the period when the ground is least stable.

Specific details on tonnage limits, permitted vehicle exceptions, and the permit process were not included in the public notice, but the Iron County Road Commission directs anyone seeking that information to ironcountyroads.com, where seasonal information and permit details are available. The commission can also be reached by phone at 265-6686 or by email at info@ironcountyroads.com, with the office located in Iron River, MI 49935.
