The Denver Broncos will board fire trucks and roll slowly through the crowd-lined streets of the Mile High City to celebrate winning the Super Bowl.

Hundreds of thousands of people are expected for Tuesday's parade and rally after the Broncos defeated the Carolina Panthers 24-10 in Super Bowl 50.

Officials won't give specific turnout predictions, but the last time Denver won the Super Bowl, the downtown party drew an estimated 375,000 people. A year before that, when the Broncos won the Super Bowl for the first time, about 650,000 people showed up.

Tuesday's celebration starts at 10 a.m. with a concert in front of the City-County Building overlooking Civic Center park. The parade steps off at 11 a.m. near Union Station, arriving at the park around noon for the rally.
