Plan Your Route

If you drive through uptown Saint John, you need to plan a different route. The closure spans Water Street between King Street and Princess Street. The street shuts down completely in both directions, 24 hours a day, for the duration of the project.

The city set up detours to guide you around the construction zone. You should use Union Street, Crown Street, or Broad Street as alternative routes. Expect to see road and sidewalk directional signs. Drive cautiously and watch for pedestrians and construction workers.

Businesses Remain Open

Local shops and services in the construction zone stay open. You can still access your favorite Water Street businesses while the work takes place.
