The One Day You're Allowed to Walk the Mackinac Bridge

For one morning each year, Michigan's longest bridge belongs to nobody but pedestrians. Every Labor Day, four lanes of highway traffic across the five-mile Mackinac Bridge go silent, and tens of thousands of people cross it on foot - something that would get you arrested any other day of the year.

A Walk That Started With 68 People

The tradition began in June 1958, during the dedication of the newly finished bridge. Michigan's governor led a small crowd across it on foot - but only 68 people actually showed up.

The walk moved to Labor Day the following year. For a while, the starting point alternated between the Upper and Lower Peninsulas each year, so no side of the state got to call it "theirs."

From Dozens to Tens of Thousands

The crowd kept growing. By the bridge's 50th anniversary in 2007, roughly 60,000 people turned out.

In an average year now, 40,000 to 65,000 walkers make the crossing. The record came in 1992, when an estimated 85,000 people walked the bridge in a single morning.

The Whole Bridge, Not Just Two Lanes

For decades, the walk shared the deck with cars. Two lanes stayed open to vehicle traffic while walkers used the rest of the bridge.

That changed in 2017. Now the entire span closes to public vehicle traffic for the event, and even shipping and boat traffic below the bridge pauses while walkers are overhead.

The walk has only been called off once. In 2020, Michigan cancelled it for the first time in its history, citing the pandemic and a drop in bridge toll revenue. It resumed the following year.

How to Join the 2026 Walk

The next Bridge Walk is set for Monday, September 7, 2026. The bridge closes to public traffic from 6:30 a.m. to noon.

Walking begins at 7 a.m., once the governor's party starts across. Nobody is allowed to start after 11:30 a.m., and the average crossing takes about two hours.

There's no registration fee. Walkers can start from either end - St. Ignace in the Upper Peninsula or Mackinaw City in the Lower Peninsula - and some do the full ten-mile round trip just to say they finished. Everyone who completes it gets a numbered certificate.

For one morning, the Mighty Mac stops being a highway and becomes a five-mile sidewalk between two peninsulas.
