Las Vegas currently has two ferris wheels in construction. Caesars Entertainment has Linq, situated in the middle of the Strip. To the south, near Manadalay Bay, there's Skyvue. But recent reports indicate that the Skyvue Ferris Wheel project may be in financial distress. Eight different companies that have worked on the Skyvue have filed liens for their work.

The question is, are two ferris wheels in Las Vegas overkill?

“Heck yes,” says Las Vegas Review Journal’s Howard Stutz. “London’s got the most famous observation wheel, the London Eye. Singapore’s got an observation wheel. Obviously they’re cities much larger than Las Vegas, and they only have one observation wheel – why do we need two?”

The "London Eye." Caesars' "High Roller" ferris wheel will be 550 feet tall, compared to the London wheel's 443 feet.

Developer Richard Marin says his Staten Island ferris wheel will be the world's largest, at 625 feet. It's part of a development that will include an outlet mall and a hotel.  Although the wheel will be situated in a flood zone, Hurricane Sandy prompted only minor changes to Marin's plan.  (Photo New York Wheel, LLC)
