2021 Was Another Record Breaking Year For Mackinac Bridge Traffic

Mackinac Bridge Sheplers Ferry Tour

The Mackinac Bridge has been an iconic Michigan landmark since 1957, connecting the Lower Peninsula to the Upper Peninsula and providing millions of travelers one of the most scenic five mile drives in the state. The Mackinac Bridge Authority recently posted final statistics for December of 2021 so we can now go back and take a look at what was a record breaking year. Since the bridge has made a few headlines recently for scary things like a crash that left a truck hanging on the side of the railing and a 12 foot trailer that tipped over during a high wind advisory, it seemed like a good time to highlight some good news about Michigan’s favorite bridge. With 4,386,466 vehicle crossings in 2021, the Mackinac Bridge had a 16.8% increase from 2020 and a 3.72% increase over 2019 which was its previous busiest year. 2021 also saw a new single month record, which we will look at below. Overall, it was great to see numbers rebound after COVID-19 slowed things down in 2020. Here’s a look at our deep dive into the numbers provided by the Mackinac Bridge Authority at https://www.mackinacbridge.org.

The variance in 2020 is easily explained by COVID-19 travel restrictions. With that lone exception there has been an increase in bridge traffic each year. Now let’s look at how the year broke down month by month:
