The Baltimore Ravens announced Thursday a two-year, $35 million investment that will enhance the fan experience at M&T Bank Stadium with improvements to video boards, concession stands and all concourses.

The first phase of improvements will begin this spring, with extensive upgrades to the stadium’s lower concourse and video boards to be completed before the Ravens’ 2013 preseason home opener. The second phase of work, which will target the upper concourse, is scheduled to begin in 2014.

"We are striving to make the fan experience at Ravens’ home games and other stadium events the best it can be," Ravens team president Dick Cassstated. "This is something that the NFL emphasizes with all teams and has been a top priority for the Ravens since opening the stadium 15 years ago."

"There is wear and tear that comes with every season, and these improvements will certainly benefit our fans and our business," Ravens vice president of stadium operations Roy Sommerhof said. "Our hope is to complete these projects over the next two years."
