The Mackinac Bridge feels like a suspended sentence written in cable and steel, and the first time I crossed it I was a kid in the backseat of my dad’s old station wagon watching my mom’s knuckles go white on the wheel. The car drifted sideways in a gust without her touching the steering at all. I remember the hum, that metal-grate vibration you feel in your molars before you hear it in your ears, and the straits looked absurdly huge from that height with blue folding into blue at the edges. I pressed my forehead to the cold glass and understood, in a way I did not yet have words for, that a bridge is not a road. A bridge is a road draped across a river of air that has its own ideas about where your car should be.
Years later I led a convoy across a similar span in a fraction of that wind, and I still panicked in front of everybody.
The accordion I caused
The sky was the color of wet concrete and I had a neat chain of cars stacked behind me when the deck started swaying and my brain did the stupid thing and told me to brake. It was not a hard stop. Just that instinctive protective tap your body does when it is surprised by motion underneath you. The problem was that everybody behind me also braked, and the driver at the back braked harder because they were reacting to brake lights rather than wind, and by the time the accordion unfolded through the group the last car was almost stopped in a travel lane with a semi roaring past in the other direction. My friend in the back still brings it up at parties with the exact kind of affection that tells you she is never going to let me forget it.
Wider spacing, because the deck is alive
The Mackinac Bridge Authority publishes specific wind thresholds for their span, escorting high-profile vehicles across in moderate gusts and closing the bridge entirely when the wind climbs high enough to make physics ungovernable. A crosswind on a long span turns a car into a kite with wheels, and the longer the deck, the longer you are exposed to the push of it.
Your reaction time stretches on a bridge in wind because the surface is moving underneath you and your vehicle is responding to inputs you are not making with your hands. You need more room to absorb a gust, more room to absorb a stranger’s panic brake, more room to absorb your own if the deck sways in a way you were not ready for. The instinct to keep the group visually tight is exactly the wrong impulse out on a long span in weather. You cannot safely open spacing once the deck is humming under you, which means it has to be arranged before the on-ramp while you are still on asphalt that stays put. A bridge is not where you enforce neatness, it is where you give everybody room to be a little bit wrong without it costing anybody a bumper or a nervous system.
Pulling over on a long-span bridge is not really an option, because the shoulder is narrow or nonexistent and stopping creates a new problem bigger than whatever made you want to stop in the first place.
My friend Priya rode with me across a long causeway one winter and I did not know until we were already on it that she carried a gut-level fear of long bridges over open water. She asked me, very quietly, to talk to her about anything that was not the water underneath us right at that moment. I told her about a bakery I loved in Lisbon with tiles the color of the sky we were under, and the warm yeasty smell of the shop in the early morning with the ovens running hot. The talking did not stop until we hit land on the other side, and Priya exhaled like she had been holding her breath the whole way across the span. What I learned that day was a thing no safety brochure would ever bother putting in print.
Your convoy is not just a collection of cars moving in a line, it is a collection of people, and some of them are quietly struggling on bridges you thought were easy enough to ignore completely.
Toll plazas, the ambush at the end
After all of that, after you have made it across with your spacing deliberate and your group composed, a toll plaza appears like a boss level nobody warned you about, with lanes splitting in multiple directions and some of them closed and only revealing this a few seconds before the gate. Call the lane early, together, and let the group drift toward it gradually on the approach instead of lurching at the last moment before the arms come down. Coordinating cars into the same toll lane by group text at highway speed is precisely how phones end up in laps and eyes end up off the road, which is the opposite of what a bridge crossing should produce. A tool built for live location sharing during group drives shows you where everyone is sitting before the split, which is all you really need to pick a lane without having a conversation about it. For the longer version of what happens when a group actually gets separated in a moment like this, I wrote about the mechanics of a convoy split elsewhere, because the toll plaza version is the same problem wearing a different outfit.
Cross it like you mean it, then stop talking about it and drive.
