On March 15, 2014 the final upper deck bleachers and concrete bleacher-support girders (on the northwest side of the Metrodome) were brought down, taking away any standing remnants of the exterior stadium walls. On April 11, 2014 the final portion of the inner-stadium concrete walls were reduced to rubble, marking the official end of the Hubert H. Humphrey Metrodome. Demolition of the Metrodome was formally declared complete six days later--a month ahead of schedule—as the final truckload of rubble was loaded up and removed from the new stadium construction site. Officials from Mortenson Construction said the entire demolition job required 4,910 truckloads and 16,000 man hours to complete the job.
