If everybody had an ocean, across the U.S.A, they'd be too busy building floating bridges to play on silly surfboards. Floating bridges are indispensable tools for spanning areas other bridges can't. Ready to take on our bridge challenge?
They will float your boat -- and bridges, too! They're pontoons, watertight vessels used for boats and types of construction.
Perhaps the first words spoken as the Hood Canal Bridge sank: "Um, guys, did someone leave the watertight hatch open on that pontoon? Uh oh."
It's kind of an awkward name for a bridge that's in an awkward and congested area. The Governor Albert D. Rosellini Bridge -- Evergreen Point is the world's longest.
It was a distance that no traditional bridge could span. At 1.4 miles this floating bridge is an engineering marvel.
Finished in 1963, it was a counterculture bridge before it was cool to be counterculture.
Hard as it may be to believe, engineers didn't build this mammoth structure in a way that would help it survive a 20-year storm.
Hopefully, they were whisky barrels that were dutifully emptied first. Today, the bridge uses plastic, styrofoam-filled barrels.
You might get tired of walking before you cross the 1,200-foot (366-meter) length of the Eastbank Esplanade in Portland, Ore.
Steel or no steel, the Demerara Harbour Bridge in Guyana has often lacked consistent maintenance and has been closed several times.
Is there such a thing as a waterquake? Although the floating parts are generally safe, the land-based approaches can succumb to shaking ground.
What's that saying about Mother Nature always winning in the end? The enormous cables were 3 feet in diameter, yet they still broke.
Say you want to conquer a group of people, but they're on the other side of a deep lake or river. What do you do? Build a floating bridge! That's what many ancient military leaders did.
It literally means "Sea of Hell," and it enraged Xerxes by destroying the first floating bridge his men constructed.
They needed almost 400 boats to complete the task. And thankfully it worked, so the engineers didn't have their heads lopped off like the first bunch.
Water is great; too much is not. High water levels forced the first closure in the bridge's 10-year history.
This floating bridge is also a critical Interstate route, as part of Interstate 90.
And if you don't pay, they will find you. Many owners designate these as toll bridges until they recoup much of the construction cost.
You want a bridge? We'll build you a bridge -- in 300 days. It was an amazing technological feat.
Its length of 1,181 feet (360 meters) makes its 300-day construction timeline even more amazing.
The name might make you chuckle, but the Smile will have a whopping 12 lanes for massive traffic flow.
