The Niners are planning a $600M-$800M 68,000 seat stadium to open in 2012. The stadium would be adjacent to their current home at Candlestick/Monster Park. However, the new stadium would depend on approval by the city to approve a mall/entertainment/residential complex right next to the new stadium and some officials say that might require rezoning and not be approved. If the deal falls through, the new stadium could be built in Santa Clara, about 45 miles south of San Francisco.
Here’s a computer illustration of the new Niners stadium.
