MINNEAPOLIS (AP) - The Minnesota Vikings are celebrating another milestone in the construction of their new $1.08 billion stadium in downtown Minneapolis.

The team and stadium contractor Mortenson Construction held a "topping out" ceremony Thursday. That's when the highest or last steel beam is placed in a building under construction.

Reports say stormy weather delayed the scheduled raising of the final beam at U.S. Bank Stadium. The Minnesota Sports Facilities Authority says the beam will be raised Friday.

Workers signed their names on the last beam. The crowd also observed a moment of silence to honor Jeramie Gruber, a roofer who fell to his death at the site last month.

Construction officials say the stadium is on schedule to be completed for the start of the Vikings' 2016 season.
