MINNEAPOLIS (AP) -- The Metrodome's new roof is up again.
Stadium officials and construction workers have completed a test inflation of the Teflon-coated ceiling. Chief engineer Steve Maki says the process was problem-free. It took about an hour Tuesday morning. The project is scheduled to be finished in a few weeks, in time for the Vikings to play their first preseason game.
Workers were inside with poles to make sure the inner lining didn't get caught, and others were harnessed to the top of the roof to monitor the slow rise.
The work began in March. The old roof collapsed in December under the weight of snow during a heavy storm, forcing the Vikings to play their final two home games elsewhere.
The roof replacement cost about $23 million. It's covered by insurance.
