We always post current conditions and any advisories or closures on our website: https://www.MackinacBridge.org/Fares-Traffic/Conditions/. We also tweet those updates on our Twitter account: @MackinacBridge.
People who are interested in receiving text messages about bridge closures, including closure information for the Annual Bridge Walk, can sign up for Mackinac County 911’s RAVE Alert System updates. There is no cost to receive these updates, aside from any texting fees from the participant’s mobile coverage plan. To opt into this text alert system, text “MacBridge” to 67283.
As drivers approach the Mackinac Bridge, advisories are posted on our dynamic message signs on US-2 and I-75. During closures, the Michigan Department of Transportation (MDOT) helps post information on their message signs farther away from the Straits. Once in the Straits area, drivers can tune to AM radio 530 or 1610 for updates.
We also have current camera views of the bridge on our website, if that helps drivers make travel decisions: https://www.MackinacBridge.org/Fares-Traffic/Bridge-Cam/.
