The 49ers moved another step closer to new stadium Tuesday night.
The stadium authority -- comprised of Santa Clara City Council members -- voted 5-1 to support the 878 million contract that calls for building a 68,500-seat facility.
Construction on the stadium is scheduled to begin June 1 and finalized in time for the 2014 season.
As part of the vote, the construction firm Turner-Devcon was approved to build the stadium.
A group against the stadium's construction, Santa Clara Plays Fair, has collected signatures to call for a referendum on the 850 million loan.
The San Francisco Chronicle first reported the vote.
