It won't get much deeper than this. The site of the former Metrodome is now a giant hole of dirt awaiting its future as the new Minnesota Multipurpose Stadium. (With the Minnesota Vikings as the primary tenant.)
On Friday, the hole takes its first dump of a horizontal pouring of concrete. The concrete will form the lid of the loading docking.
Next week, comes a major dump: the pouring of the stadium's main concrete concourse.
The new stadium is set to open in 2016. Until then, it's a constantly evolving project with progress visible from the street..
The entire downtown east area of Minneapolis currently seems to be in teardown mode. Along with the new stadium, two parking lots formerly owned by the Star Tribune are being ripped up.
