The Chicago Bears released their conceptual plans Tuesday for a development of the 326-acre Arlington Park property, which includes the construction of a domed stadium.

Last September, the Bears took a step toward leaving historic Soldier Field when they signed a $197.2 million purchase and sale agreement (PSA) with Churchill Downs Inc. for the property in suburban Arlington Heights after the track, which has hosted thoroughbred racing since 1927, was put up for sale.

The Bears' lease at Soldier Field runs through 2033, but the team can end the lease as soon as 2026 for an estimated $84 million.
