Construction of the new $1 billion Vikings stadium hit a milestone Thursday morning with the pouring of the last concrete column.

The stadium, slated to be complete for the 2016 football season, is being built on the edge of downtown Minneapolis where the Metrodome once stood. The new 1.75 million-square-foot building will seat 65,400.

Since construction began, more than 1,200 concrete columns have gone up at the stadium site. If put end-to-end, the columns would stretch 5.3 miles, according to the Minnesota Sports Facility Authority.
