COVID-19 - STM construction sites closed until further notice

Following the announcement made by the Government of Quebec on March 23, the STM’s construction sites will be closed until further notice. We will inform you when operations start up again.

Closing construction sites does not affect the bus and métro service. The STM’s priority is to ensure continuity of service, while following public health recommendations.

Did you know that...

When a construction site requires the use of explosives near the métro network, a procedure to check structural integrity is systematically used.

First, a seismograph records measurements taken inside the tunnels on a continuous basis. Then, after every detonation, inspectors specialized in structural engineering walk through to carefully inspect the tunnel walls.

This means that service interruptions lasting a few minutes are required for the inspectors to complete their work and ensure the network’s longevity and overall safety.

Thankfully, these preventive measures usually take place during off-peak hours and are conducted over very short periods of time.
