Yep, did the Mackinac bridge this summer. For sure if you can stay on the paved right lane. Thing is there is always construction on this thing so odds are you will end up on the grates. Really was not so bad grates are well maintained and fairly close together. Now in bad weather it would be much worse.


By far worst bridge I have ever crossed is the Irving S Cobb bridge that connects Brookport IL to Paducah KY over the Ohio river. Narrow, one lane each way, all grates with huge openings in the grates (Pics of people dropping a pop can freely between the grate openings). You feel very exposed on the bridge, about 1.75 miles of white knuckle fun!
