SANTA CLARA (BCN) — Super Bowl fans planning to take Santa Clara Valley Transportation Authority train or bus service to Levi’s Stadium will need their game ticket

and a pre-purchased mobile ticket to get to the game, transit officials said.

The pre-purchased mobile ticket, called an EventTIK, must be purchased with a smartphone on the iTunes app store or the Google Play store for those with Android phones.

Proof of purchase is an activated image on the phone. VTA fare will not be sold at the stadium, according to transit officials.

Only 12,000 EventTIKs are available, so transit officials are encouraging people to buy them as soon as possible.

The cost of the ticket is $20 or $40 when combined with a Caltrain ticket, transit officials said.

The number of passengers is being limited to allow the system to operate efficiently and safely and because of the heightened security around the game, which is considered a special security event by the Transportation Security Administration.

VTA is the only transit service that goes directly to Levi’s Stadium, according to transit officials.

Inspectors will be asking fans to show both tickets as they board trains at designated stations for the Super Bowl and at the Fremont BART station where express bus service will run to the stadium.

Transit officials will also be enforcing the NFL’s bag policy, which limits the size or volume of bags brought into stadiums, according to the NFL’s website.

Bags that can be brought into a stadium include bags that are 12 by 6 by 12 inches in size or plastic bags one gallon in size or small clutch bags, such as ones that can fit in a person’s hand, the NFL’s website says.

Trains from Mountain View, which connect with Caltrain from San Francisco, will off-board at Great America Station for the game and trains from south of the stadium, such as those from San Jose and Milpitas, will off-board at Lick Mill Station.

Passengers should plan to leave the stadium from the same station at which they arrived, transit officials said.
