SIOUX FALLS, S.D. (Dakota News Now) - A new downtown convention center in Sioux Falls could cost up to $250 million, according to a draft report presented on Tuesday by Johnson Consulting to the Riverline District Steering Committee.

The City Council already approved $8 million to buy land near the 10th Street viaduct.

Consultants estimate the project could bring in up to $55 million a year in economic impact and create over 200 jobs.

Plans also include converting the current convention center into an indoor recreation space if the downtown project moves forward.
