Transport Quebec announced that Highway 13 in the Chomedey district and the Highway 520 interchange at Côte‑de‑Liesse will be closed overnight from September 28 through November 2, 2026. The closures are scheduled to facilitate the continuation of reconstruction work on the Highway 520 overpass.
The overnight shutdowns will affect traffic on the north‑south corridor of Highway 13 as well as the east‑west movements at the Highway 520 interchange. Drivers are advised to plan alternate routes during the hours when the closures are in effect. The exact timing of the nightly work periods has not been detailed, but the restrictions will remain in place each night for the entire 36‑day window.
Transport Quebec indicated that the overpass reconstruction, initially slated for a shorter duration, has been extended, prompting the need for additional temporary road closures. Extending the project allows crews to complete structural repairs and surface work without the constraints of daytime traffic.
The agency’s decision aligns with broader efforts to maintain and upgrade Montreal’s transportation infrastructure. By concentrating work during nighttime hours, Transport Quebec aims to minimise disruption to the weekday flow of commuters while ensuring the safety of construction personnel. Motorists traveling through the Chomedey and Côte‑de‑Liesse areas are encouraged to stay informed of any updates released by the department throughout the construction period.
The closure plan will be in effect until the evening of November 2, after which normal traffic patterns are expected to resume pending final inspections of the overpass. Residents and commuters should monitor local traffic advisories for any changes to the schedule or additional guidance as the project progresses.
