St. Louis has revealed plans for a new open-air football stadium along the Mississippi River.

The city is trying to improve its bid to keep the St. Louis Rams, who are considering relocating to Los Angeles.

The stadium would cost at least $860 million, but there reportedly would be no new tax burden to build the 64,000-seat venue. Private sources and seat licensing fees would pay for more than half, while other funding would come from tax credits and other public financing.
