Frequently asked questions about the measures

The mitigation measures for repair work on the Louis-Hippolyte-La Fontaine Tunnel started on the A-20 on December 13, 2021, and will remain in place throughout the duration of the work.

Repairs began in summer 2021 and will continue until 2026.

Note: the major closures end in 2025.

This is the duration determined by the MTQ.

The work began in summer 2021: detours, night and weekend closures on the A-20, minor closures of the local network and occasional weekend closures of the tunnel have affected South Shore traffic.

From 2022 to 2025, you can expect significant impacts on both northbound and southbound traffic.

To follow the progress of the work and find out about upcoming closures, visit the website dedicated to the project.

Repair work on the Louis-Hippolyte-La Fontaine Tunnel will affect the following sectors: exo Sainte-Julie (routes 325, 330, 340, 350 and 600), exo Vallée-du-Richelieu (routes 201 and 300) and exo Sorel-Varennes (routes 709, 710 and 722).

While the work may cause delays, the mitigation measures established by the ARTM and carried out by exo will allow us to limit impacts on passengers.

These lines are free for the duration of the work.

As a public transit agency, exo is responsible for executing the mitigation measures established by the ARTM.

Exo will continue to study ridership data to determine if additional mitigation measures are necessary. If need be, we will propose new services to the ARTM, the agency responsible for establishing the necessary mitigation measures.
