Aug 1-3: 7 Avenue Closure - Red & Blue Line service disruptions

Affected routes: Red Line, Blue Line

Affected stations:
8 Street, 7 Street, 6 Street, 4 Street, 3 Street, 1 Street, Centre Street, City Hall/Bow Valley College

Affected service hours:
Saturday, August 1 (all day)
Sunday, August 2 (all day)
Monday, August 3 (all day)

What's the short version?:

From Saturday, August 1 to the very early hours of Tuesday, August 4, 2026, all downtown stations along 7 Ave S between City Hall/Bow Valley College Station and 7 St SW (7 Street & 8 Street Stations) will be closed. Shuttle buses will replace CTrain service between the affected stations. With 7 Ave S closed, the shuttles will be running westbound along 6 Ave S and eastbound along 9 Ave S. Full CTrain service is scheduled to return by start of service on Tuesday, August 4.

Replacement shuttles will run a single route, serving both the Red and Blue Line. If you’re transferring to a north or westbound CTrain, get off the bus at the stop on 7 St SW @ 8 Ave SW, where you can access both 7 Street and 8 Street CTrain stations. 

What to expect:

  • The Red Line will be closed between City Hall/Bow Valley College and 8 Street stations with shuttle buses providing replacement service through downtown:
    • Heading south (toward Somerset-Bridlewood):
      Transfer to the southbound Red Line CTrain at City Hall/BVC Station.
    • Heading northwest (toward Tuscany):
      Transfer to the northbound Red Line CTrain at 8 Street Station
      • NOTE:  while it is technically an eastbound station, 8 Street will be the terminus station for the north Red Line CTrain during this closure. Red Line trains will come in to downtown from the northwest as usual, then change direction there and head back northbound from 8 Street Station.
  • The Blue Line will be closed between City Hall/Bow Valley College and 7 Street stations, also with shuttle buses providing replacement service through downtown: 
    • Heading northeast (toward Saddletowne):
      Transfer to the eastbound CTrain at City Hall/BVC Station.
    • Heading west (towards 69 Street):
      Unlike the Red Line, you’ll transfer to the westbound Blue Line CTrain at 7 Street Station instead. 

Full CTrain service downtown is scheduled to be back up and running again by start of service on Tuesday, August 4.

What’s happening?:

Some of the projects on the list this long weekend include:

  • In-street track replacement on 7 Ave at 3 St SW and 4 St SW
  • Work on the overhead catenary system
  • Follow up on projects from May long weekend
  • Plus a number of other projects, as time allows.

Thank you for your patience during this closure!

Why are we doing all of these closures?

We know CTrain closures can have an impact on your travel, which is why we try to keep them as minimally disruptive as possible. That’s also why they’re so important - because doing preventative work and maintenance now can ensure we’re providing Calgarians with a safe, reliable, and efficient transit system.

Some work can be completed while keeping the trains on track, but there are certain projects that are just too big, or can’t share the space safely while trains are in service, and they require fully closing off sections of the line. Occasionally, a power cut is required to carry out specific work, which also means we need to close the line to train travel.

During the planning stage, we try to consolidate projects where can to minimize how often we need to close a certain section of the system, and do our best to plan around major events or times of heaviest transit use. Wherever possible, we will opt for single tracking instead, to further reduce impact to service.

What is “single tracking”?

When considering the work that needs to be done at (or between) specific stations, we’ll look into whether closing just one side of the tracks is a safe, effective, and available option. Also known as “single tracking”, this type of closure allows us to complete the important work while also keeping train traffic moving!

Trains travelling in either direction will share the same track and same side of the station/platform.

So, when this happens, keep an eye on the station’s digital displays, and an ear out for the PA announcements to make sure you’re in the right spot - and don’t forget to double check the train’s destination display before hopping on!
