Work has been shut down on the 49ers' new $1.3 billion stadium after a construction worker was killed in an elevator shaft at 6:50 a.m. Exactly how the fatality occurred is under investigation, according to officials for Turner-Devcon, the general contractor for the .

There are approximately 1,000 people working on the stadium, which is due to be completed a little more than a year from now. Turner-Devcon said all workers must take a safety orientation and safety training before beginning work.

Stadium construction has been halted while Cal-OSHA interviews workers and conducts an investigation. Construction at Levi's Stadium has been around the clock since a groundbreaking ceremony for the facility in April of 2012.

The 49ers and the Bay Area recently were awarded Super Bowl L, which will be played in February 2016 at the new stadium. The 49ers will begin playing there in 2014. This is their final season at Candlestick Park in San Francisco.
The 49ers will kickoff a three-day minicamp today on their practice fields, which are adjacent to the stadium.
