St. Louis (KSDK) - We've learned that the St. Louis Rams are heading to arbitration over the Edward Jones Dome.
The St. Louis Convention and Visitors Commission voted Thursday to begin the arbitration process.
Negotiations began in February with the CVC proposing $124 million in Dome improvements.
The Rams countered with a much broader plan that city leaders say could cost $700 million.
Under the terms of the lease, if the Dome is not among the top tier of NFL facilities the Rams will be free to leave after the 2014 season.
