Boston will celebrate the Celtics' 18th NBA championship with a parade on Friday at 11 a.m., starting at TD Garden and ending near the Hynes Convention Center. The parade was delayed from midweek to avoid an extreme heat wave, with temperatures expected to be more comfortable by Friday. Mayor Michelle Wu expressed gratitude to the team for their achievements and highlighted the parade’s significance for the city's morale and economy. Thousands of fans are expected to attend, and public safety measures are in place with increased police presence and EMTs along the route. Businesses along the parade route are preparing for a significant boost in revenue as the community comes together to celebrate. The iconic duck boats will carry players through the city, continuing a Boston tradition.
