June 10, 2026 Honoré Mercier Bridge


From Friday, June 12, 11 p.m., to Monday, June 15, 5 a.m.:

  • Closure of the access ramp toward Montréal, from La Prairie.
  • Closure of the exit ramp toward Châteauguay, from Montréal.
  • Detours: see map.

Major slowdowns to be expected.
This work will involve repairing joints and several barriers.

 

Please note that this work may be cancelled or postponed depending on work progress and weather conditions.

The ministère des Transports et de la Mobilité durable will take advantage of these hindrances to carry out work on the provincial section of the bridge, in order to minimize the number of closures on the structure as much as possible.
