WASHINGTON (WUSA9) -- What makes a bridge scary?
For some commuters, the mere width can be scary enough. However, travel experts have ranked these U.S. bridges the "scariest" due to its length, height and location.

Top seven scariest bridges in the U.S.
Royal Gorge Bridge, Colorado
America's highest suspension bridge may be breathtaking for some, but those scared of heights may be left gasping for air as they stare straight down nearly 90 stories at the Arkansas River below. Completed in 1929, the bridge didn't have stabilizing wind cables until 1982.
Where: Royal Gorge, Colorado, over the Arkansas River.
Stats: 969 feet above the gorge; 1,260 feet long.
Mackinac Bridge, Michigan
Some drivers get so nervous about crossing this five-mile-long bridge that they don't even go. And this happens so often that the Mackinac Bridge Authority will drive your car or motorcycle for you (and for free). The biggest fear is the wind, which often exceeds 30 miles per hour on the bridge.
Where: Between Michigan's Upper and Lower Peninsulas.
Stats: 5 miles long; 199 feet above the water.
William Preston Lane, Jr. Memorial Bridge (Bay Bridge), Maryland
Drivers are notoriously afraid of this bridge, as it's subjected to frequent-and often violent-storms. And when the bad weather hits, forget about visibility: get to the middle of this five-mile-long bridge and you can barely see land.
Where: Spanning the Chesapeake Bay to connect Maryland's eastern and western shores.
Stats: Nearly 5 miles long; 186 feet high at its highest point.
Seven Mile Bridge, Florida
Besides being seven miles long, the bridge itself doesn't seem that scary. But its position in the Florida Keys makes it a prime target for the region's many hurricanes. In fact, the current bridge is the second iteration. The newer bridge scrapped the swing span concept of the original in lieu of a sturdier 65-foot-high arch to allow boats to pass by. While it may be sturdier, we still wouldn't want to be on it during a storm.
Where: The Florida Keys, connecting the Middle and Lower Keys.
Stats: 7 miles long; 65 feet high.
Deception Pass Bridge, Washington
If the drive over this foggy strait in the Puget Sound isn't particularly scary to you, try walking over the narrow pedestrian lane at the edge of the bridge. That's where you'll find especially hair-raising views of the rushing water directly below.
Where: Connecting Whidbey Island and Fidalgo Island, in Deception Pass State Park.
Stats: Combined, the two spans are 1,486 feet in length; 180 feet above the water.
Captain William Moore Bridge, Alaska
True, earthquakes don't happen all the time, but this bridge isn't where you want to be during one: it crosses an active earthquake fault. Engineers, aware of the potential for disaster, anchored only one end of the bridge securely, so when the ground below shifts, the bridge isn't torn apart.
Where: Along the South Klondike Highway near Skagway
Stats: 110-foot-long cantilever bridge finished in 1976
Lake Pontchartrain Causeway, Louisiana
This bridge rises just 16 feet above the waters of Lake Pontchartrain, but the real fear factor is that it never seems to end-it spans nearly 24 miles from Metairie to Mandeville, LA. (Once you reach roughly the eight-mile mark, say goodbye to land visibility.)
Where: Across Lake Pontchartrain between the towns of Metairie and Mandeville.
Stats: 24 miles long; 16 feet above water.
