Mountain View city officials are expecting 1.3 million people to come through the area for Super Bowl 50.
The National Football League's biggest game is set to be played in Santa Clara's Levi's Stadium next month. Excitement for the game have city and transportation officials bracing for the influx of traffic.
Part of Castro Street, along with parts of nearby West Evelyn Avenue, will be closed on Super Bowl Sunday to help curb traffic, city officials said.
Mountain View is also calling itself the transit hub. City officials expect to see "hectic" traffic on Super Bowl Sunday as fans work their way to Levi's Stadium.
Mountain View police are urging people to arrive early to take the train and to not leave any valuables in their vehicles.
