Thousands of fans celebrate the Washington Capitals' 1st Stanley Cup win

A sea of red filled Constitution Avenue as fans celebrate the Capitals win.

A sea of red filled Constitution Avenue in Washington, D.C., on Tuesday as fans celebrated the Washington Capitals first Stanley Cup win.

Dressed head to toe in red, fans lined the victory parade route that ran down Constitution Avenue and concluded with a rally at the National Mall.

A number of buses carried the team and their family members, the last bus hosted Ovechkin who held the trophy in the air as fans cheered.

“This happens because they support as much as you are,” Ovechkin said at the rally. “We want to say to our families and you guys, 'thank you very much.'"

Thousands of fans attended the event and one Twitter user joked that people in Washington, D.C., likely avoided going to work to attend the celebratory occasion.

At the rally, right winger T.J. Oshie teased that the Washington Capitals would win back-to-back championships, which garnered a roar of applause from the crowd.

Before the end of the event, the team and crowd sang, “We are the Champions” and chanted, “Let’s go Caps!”
