The Quebec Ministry of Transport announced that the Honoré-Mercier Bridge will operate with a single lane for traffic in each direction from July 17 through August 3, 2026. The temporary lane restriction is part of extensive summer repair work scheduled on the structure that connects Montreal to the South Shore.
During the two‑week period, only one lane will be available for vehicles traveling both eastbound and westbound across the bridge. Motorists are expected to encounter slower travel times as the reduced capacity forces all traffic to share the same lane in each direction. The ministry cautioned that the change will likely lead to significant congestion on the bridge, which serves as a key commuter artery for residents moving between the city and the Rive‑Sud.
The work is described as a major construction effort aimed at addressing the bridge’s maintenance needs during the summer months. By concentrating repairs within a defined window, the ministry hopes to complete the necessary upgrades while minimizing the overall disruption to the transportation network. The timing coincides with the typical summer travel season, when many commuters rely on the bridge for daily trips.
Travelers are advised to plan for longer travel times and to consider alternative routes where possible. The ministry has not provided additional details on the specific repair activities but emphasized that the lane reduction is essential for safely carrying out the work. The bridge’s importance to the regional traffic flow means that even a short period of reduced capacity can have a noticeable impact on commuter patterns.
The Ministry of Transport will continue to monitor traffic conditions throughout the construction window and may issue further updates if circumstances change. Motorists are encouraged to stay informed through official channels and to adjust their travel plans accordingly to accommodate the temporary lane configuration.
The Honoré-Mercier Bridge is expected to return to normal two‑lane operation for both directions after August 3, when the summer repair project is slated to conclude.
