The closure will have an effect on the part between the Decarie interchange and the doorway from Jean-Talon Avenue to Freeway 15 southbound. The work is required to exchange a bit of a beam on the de la Savane overpass and to hold out beam repairs on the Des Jockeys and Ferrier overpasses.

  • The ramp from Marcel-Laurin Boulevard (Route 117) to Freeway 15 southbound, from Friday at 10 p.m. to Monday at 5:30 a.m.

Delays anticipated; drivers urged to plan forward

Detour routes will probably be marked with non permanent signage, and congestion is predicted within the space.

The ministry advises motorists travelling within the sector to permit additional time to succeed in their vacation spot.

The work could also be postponed, prolonged or cancelled on account of climate circumstances or operational constraints. Drivers are inspired to examine Québec 511 earlier than heading out and to obtain the cell utility for updates and notifications.
