Work to replace Fourth Avenue sewer main in Kamloops to stretch into 2026

KAMLOOPS — Work to upgrade the sewer main along Fourth Avenue in downtown Kamloops will stretch over into next year’s construction season.

In an update Friday (Oct. 24), the City of Kamloops said crews are currently scheduled to pave the section of Fourth Avenue between Seymour Street and St. Paul Street on Monday and Tuesday (Oct. 27 and 28) next week.

Seymour Street, which was briefly reduced to one lane, has reopened and the section of Fourth Avenue south of Seymour Street to St. Paul Street is expected to reopen to traffic once this paving work is complete.

According to the city, crews are also scheduled to do some “preliminary work” between St. Paul Street and Battle Street from Wednesday to Friday (Oct. 29 to 31) next week.

On those three days, that one block section of Fourth Avenue will be closed to traffic during the day, though it will reopen in the evenings.

“Work on Fourth Avenue for the 2025 construction season will wrap up at the end of October,” the city added. “Crews will return in spring 2026 to complete work from St. Paul Street to Battle Street.”

Work to upgrade the sewer main along Fourth Avenue began at Lansdowne Street in early July 7. Crews were initially expected to wrap up at Battle Street in early November this year.

This sewer main project – which builds off last year’s work along Lansdowne Street – is being done to upgrade capacity downtown for the City Gardens development as well as the Kamloops Centre for the Arts which is set to begin construction soon.
