An official celebration marking the Super Bowl Victory will be held Wednesday in downtown Seattle. It will start a 11 a.m. on Fourth Avenue south of Denny Way and will arrive at CenturyLink Field around 1:30 p.m.
No parking signs are already up along the parade route and businesses are gearing up for the throngs of fans. Staff at the Purple Caf and Wine Bar may hang Seahawks banners in their huge windows and cheer the team on as they pass.
"We're all very excited, and that parade's going to be the culmination of a long-time super bowl win waiting to happen," said Michah Denunzio of the cafe.
City officials say people can begin lining up on the sidewalk as early as they want on Wednesday. Officials are expecting 200,000 to 300,000 people to line the route.
The superintendent of Seattle Public Schools says parents can take their kids out of school for the victory parade - but it will be an unexcused absence.
