If you think about the most scenic roads in Michigan what comes to mind? The Brockway Mountain Drive in the Keweenaw? A crossing of the Mackinac Bridge or the highway you can't actually drive on, M-185 around Mackinac Island

How about the iconic Tunnel of Trees the roadway from Harbor Springs to Cross Village, M-119, is famously covered with a thick canopy of foliage for nearly the entire roadway.

It's the Tunnel of Trees that is in a nationwide vote for most scenic roadway in America. Being conducted by Scenic America and running through March, the bracket-style tournament pits 16 scenic byways to whittle down to a champion byway.

It's David vs Goliath.

Should the Tunnel of Trees prevail, it would square off against the winner of the match-up between California's Big Sur Coast Highway and Newfound Gap Road, a scenic parkway in the Smokey Mountains.

Voting is happening in an online bracket and if you've never driven the Tunnel of Trees, there are countless videos online. Here are some autumn views.
