People fell into the Cachoeira River when a sidewalk on Avenida Beira Rio collapsed during the opening ceremony and the ceremony was interrupted for 40 minutes, Joinville City Council said in a statement.
21 adults and 12 children were taken to a local hospital but no one was injured, authorities said.
The event was then resumed and the city’s mayor, Adriano Silva, thanked emergency responders in his speech.
“We are grateful that no one is in serious condition and also that urgent care has been provided to all the victims,” the mayor said.
A team from the Department of Urban Infrastructure and Civil Defense is continuing to examine the site’s structure.
Silva convened a meeting early Tuesday morning with managers from various city infrastructure departments to determine next action steps following the incident.
