The Steelers beat the Seattle Seahawks 21-10 on Sunday in Super Bowl XL in Detroit to claim its fifth NFL championship and first since 1980.
On Tuesday, thousands of Pittsburgh football fans decked out in black and yellow crowded the downtown area and stood in frigid temperatures and snow flurries to honour the champion Steelers.
Coach Bill Cowher and the players rode along the parade route in the back of pickup trucks and other cars. Also taking part in the festivities were Mayor Bob O'Connor and Pennsylvania Governor Ed Rendell, a die-hard Philadelphia Eagles fan.

Team owner Dan Rooney held up a sign saying "Thanks."
"This sign says it all and it's for you. Thank you," Rooney told fans. "The press, they had their doubts, but you never did and we thank you."
"Thank you guys so much. This has been a dream come true for all of us," Steelers quarterback Ben Roethlisberger told the crowd.
Fans soaked up the atmosphere and relished the moment.
"It's been 25 years or however long it's been," said Jeff Krieger, a lifelong Steelers fan. "It might be another 25 years. You never know."
The last major pro sports franchise in Pittsburgh to win a league championship were the NHL's Penguins, who won back-to-back Stanley Cups in 1991-92.
An estimated 90.7 million people watched Sunday's game, the largest Super Bowl audience in a decade. Approximately 94.1 million people watched the Dallas Cowboys beat the Steelers in the 1996 Super Bowl.
Roughly 86.1 million people watched the New England Patriots beat the Philadelphia Eagles last year.
