Missouri Gov. Jay Nixon announced deals with a power company and railroad Tuesday that he said represent ''concrete progress'' in plans to build a riverfront stadium that could help St. Louis remain an NFL city. Nixon held an outdoor news conference in near-freezing temperatures along with leaders of Ameren Missouri and Terminal Railroad Association at the proposed site for the 64,000-seat, open-air stadium that would replace the Edward Jones Dome, now 20 years old. Ameren would relocate transmission towers and the railroad would move tracks out of the stadium footprint, which Nixon said was mostly vacant lots and empty buildings in a blighted area just north of the dome. Billionaire team owner Stan Kroenke is part of a joint venture that announced plans earlier this month for an 80,000-seat stadium in the Los Angeles suburbs.
