A large boat coming from lake Michigan passes through a railroad bridge, with a road bridge up ahead. It looks like it’s going to be a squeeze getting the boat through those narrow waterways. I wonder what it’s carrying?

And the nominees for this year’s Google Sightseeing ‘Coolest Looking Bridge Shadow’ Award are as follows…

Ironcladlou for the wallet-burning Verrazano-Narrows Bridge in New York, New York.

Punk floyd, Greg Small, Duane Homick, PegO and TZ for the fantastic Ambassador Bridge which links Windsor, Ontario with Detroit, Michigan. (Windsor is on the south and Detroit is on the north side of the river.)

Steve Hale for the the world’s (second) tallest suspension bridge, the Fred Hartman bridge in Baytown, Texas.

But the winners are… (Drum-roll please!)

Tim, Dave Isaacs and khendron for the 1.6-mile-long Francis Scott Key Bridge in Baltimore, Maryland!

Congratulations guys!

Reader Tim Gregory found the 80 foot tall world’s largest tyre in Michigan. It apparently started life as a giant tyre-shaped ferris wheel at the 1964-65 New York World’s Fair, and was moved to Allen Park, Michigan to be a roadside attraction in 1966. According to this page at roadsideamerica.com it was once punctured with the world’s largest nail as a publicity stunt.

The Mackinac bridge (which connects the lower and upper peninsulas of Michigan) is the 3rd largest suspension bridge in the world. At five miles in length, it is the third-longest suspension bridge in the world.

Seriously, check it out… it’s pretty big. There’s actually a traffic jam on there too.

Thanks to Ryan, Soyle Mycelf, Otterpop and Parker. More info about the bridge is available at mackinacbridge.org.
