Vista Tower reached its final height on Friday, when construction workers poured concrete to form the Chicago skyscraper's 101st and final floor.

That marked the highest point of construction in Chicago in more than a decade, and it brought Chicago's Magellan Development Group closer to its planned spring 2020 completion of what will become the city's third-tallest skyscraper.

Topping out the 1,191-foot-tall Vista Tower came more than a decade after Trump International Hotel & Tower reached its full height in August 2008, in the throes of a real estate crash. Trump's 1,389-foot-tall condo and hotel tower, Chicago's second-tallest building, was completed in 2009.

The 1,451-foot-tall Sears Tower, now called Willis Tower, topped out in May 1973 and was completed the next year. It was the world's tallest building for 24 years, but has since been surpassed by 16 skyscrapers -- all but one of which are outside the United States.

Magellan and its Chinese investment partner, Dalian Wanda Group, broke ground in September 2016 on the $1 billion Vista project. The Jeanne Gang-designed condominium and hotel tower is near the Chicago River and Lake Michigan, at 303 E. Wacker Drive.

Here is a look at Vista Tower by the numbers.

The condo count has decreased from an originally announced 410, because some buyers have combined multiple units. 192 Number of hotel rooms planned in the low-rise portion of the skyscraper. $840,000 The lowest price among pre-sold condos. $18.5M The highest price of a pre-sold unit.
