SIOUX FALLS, S.D. (AP) — The roof is being raised over a $117 million events center being constructed in South Dakota's largest city and the facility should be fully enclosed by the end of November, in time for winter weather.

The Argus Leader reports the six main trusses over the 12,000-seat Denny Sanford Premier Center in Sioux Falls started going up at the end of July, with one installed each week. A seventh, smaller truss will be the last to be installed.

Jason Miranowski with Mortenson Construction says the project is on schedule and under budget. He says that by late November officials should be able to nail down a completion date in the fall of next year.

City Projects Manager Kendra Siemonsma says event bookers are eyeing September 2014 as the target date.
