The Las Vegas Strip is getting the world's largest Ferris wheel.
With the outer wheel of the 55-storey High Roller ride hoisted into place, the gargantuan project is now visible from all over the city, including the airport. Early next year, it will be fitted with 1,500 LED lights and start its slow spin.
"It's going to be an icon," said project director David Codiga. "It's going to be a part of your visit to Las Vegas if you ride it or not."
Caesars Entertainment is building the ride as part of a 550 million-dollar (£355m) development across the road from Caesars Palace.
The High Roller will be 100ft taller than the London Eye, which opened in 2000, 30ft taller than China's Star of Nanchang, which opened in 2006, and 9ft taller than the Singapore Flyer, which opened in 2008.
These giant urban Ferris wheels typically transport riders in large, fixed capsules instead of the smaller, teetering baskets some people remember from childhood.
The Las Vegas ride will take 30 minutes to make one revolution.
Tickets will be comparable to the London ride, which costs £19.20, according to Caesars spokeswoman Christina Karas.
But the High Roller will probably have to surrender its tallest in the world title before long. Another monster wheel is looming in New York City, where mayor Michael Bloomberg announced plans last year for a 625ft ride on the waterfront.
