The Michigan State Police is warning travelers of delays expected near the Mackinac Bridge on Labor Day.

Because of security concerns the Mighty Mac will be closed from 6:30 AM-12 Noon, to allow walkers to participate in the Annual Bridge Walk. The walk usually draws between 30,000-60,000 walkers. Gov. Rick Snyder will lead the walk as Michigan Governors have done since its beginning in 1958.

Normally, about 9,500 vehicles cross the bridge on Labor Day morning. These vehicles will now be denied passage until 12 Noon. Because of this, a back-up of traffic is expected on roads leading to the bridge. Northbound I-75 will be closed at Exit 337, and southbound I-75 and US-2 will be closed at Exit 344. Access may also be restricted on I-75 north of Gaylord, in order to limit the number of motorists stranded on the freeway. Portable bathrooms are being placed along US-2 for several miles west of the bridge, water and snack stations will be located on US-2 and I-75 north and south of the bridge. Mackinac Bridge Authority mechanics will patrol both sides of the bridge to assist motorists with vehicle problems.

"Our best advice for motorists planning to travel these impacted roads is to travel prior to 6:30 a.m. on Labor Day or to delay travel until the afternoon.” stated John Halpin, MSP Eighth District commander.
