Saint John Transit is changing the path for Route 21 South End / St. Joseph’s. If you rely on this bus, you need to know about an extended detour starting Tuesday, May 12, 2026.

Reason for the Detour

The city is starting construction on Charlotte Street. Crews will work between Queen Square North and Princess Street. This roadwork forces the detour, which lasts until October 2, 2026.

The New Path

Your bus will take a different path during this time. From King Square North, the bus turns left onto Charlotte Street. It then goes left onto King Square South and left again onto Sydney Street. From there, the bus takes a right onto King Street East, a right onto Carmarthen Street, and a left onto Broad Street before returning to the regular route.

The City of Saint John thanked riders for their patience while crews complete the project.
