The Quebec ministry of Transport and Sustainable Mobility (MTMD) announced the closure late Saturday, citing the failure of a ponceau – a type of bridge or culvert – as the cause. The compromised structure created a ample hole in the roadway,rendering the affected stretch unsafe for vehicles. This crucial transportation artery is experiencing a full closure, impacting thousands of commuters and transport vehicles daily.
Detour route and Traffic Impacts
Motorists are being diverted onto route 138 as a detour. However, this option route adds approximately 21 kilometers to the journey, compared to the 14 kilometers normally travelled on the closed section. Officials warn that Route 138 is not designed to accommodate the high volume of traffic-estimated at 37,000 vehicles per day-now being redirected onto it.
According to Louis-André Bertrand, a spokesperson for the MTMD, preliminary work is underway to enable traffic flow in both directions. The Ministry anticipates that a temporary solution to facilitate two-way traffic could be implemented within the next 48 hours, though full repairs to the damaged culvert are expected to take around two weeks.
The Laviolette Bridge in Trois-Rivières will maintain its four lanes to ensure smooth access to Highway 20, which is being recommended by the MTMD as a preferable alternative route for travelers between Trois-Rivières and Montreal.
Motorist Reactions and Updates
The sudden closure has caught several drivers off guard.One motorist, preparing for a journey to Saint-Hubert, expressed uncertainty about alternative routes. another commuter, who left early to avoid peak traffic, anticipated potential delays on their return trip.
Real-time updates on the highway closure are available on the Quebec 511 website. Check Quebec 511 for the latest information.
| Affected Area | Closure Location | Detour Route | Estimated repair Time |
|---|---|---|---|
| Highway 40 West | Between Route 158 (Berthierville) and Chemin de Joliette (Lanoraie) | Route 138 | Approximately 2 weeks |
Understanding Highway Infrastructure
Culverts, like the Ponceau that failed, are essential components of highway infrastructure.They allow water to flow under roadways, preventing flooding and maintaining structural integrity. Regular inspection and maintenance are critical to prevent failures. According to the Federal Highway Administration, approximately 40% of bridges in the United States are over 50 years old, necessitating increased investment in repair and replacement. Canada faces similar infrastructure challenges, with a growing need to modernize its aging highway network.
Frequently Asked Questions About the Highway 40 Closure
- What caused the Highway 40 closure? the closure was caused by the collapse of a culvert (Ponceau) underneath the highway.
- What is the recommended detour route? Motorists are advised to use route 138 as a detour, but be prepared for a longer travel time.
- how long will Highway 40 be closed? The MTMD anticipates the highway will be partially reopened within 48 hours, but full repairs could take up to two weeks.
- Is Highway 20 a better alternative? Yes, the MTMD recommends Highway 20 for travel between Trois-Rivières and Montreal due to anticipated congestion on Route 138.
- Where can I find the latest updates on the closure? Check the Quebec 511 website for real-time information.

Complete Highway 40 Shutdown in Westbound Direction from Berthierville to Lanoraie
Current Traffic Situation & Road Closure Details
as of 2:17 PM EST, August 24, 2025, all westbound lanes of Highway 40 are fully shut down between Berthierville and Lanoraie, Quebec. This full highway closure is due to a significant structural issue discovered during routine bridge inspections near kilometre marker 187. The Ministère des Transports du Québec (MTQ) has confirmed the closure is indefinite,with no estimated time for reopening currently available. This impacts travel throughout the Lanaudière region and significantly affects access to Montreal.
Understanding the cause of the Highway 40 Closure
The MTQ identified critical deterioration in the support beams of the overpass at kilometre 187. Preliminary investigations suggest accelerated corrosion, perhaps exacerbated by recent heavy rainfall and fluctuating temperatures. Engineers are conducting a thorough assessment to determine the extent of the damage and the necesary repairs.
Structural Integrity: the primary concern is the safety of motorists. The MTQ deemed the bridge unsafe for traffic until repairs are completed.
Corrosion Issues: Salt used for winter road maintenance is a known contributor to corrosion of bridge infrastructure in Quebec.
Inspection Protocols: The MTQ is reviewing its inspection protocols to prevent similar incidents in the future.
Detour Routes & Alternative Transportation
Motorists are strongly advised to avoid the area and seek alternative routes. The MTQ has established the following official detours:
- Via Route 138: Take Route 138 West to Saint-Placide, then connect to Autoroute 50 West towards Montreal.This is the recommended primary detour. Expect significant delays on Route 138.
- local Roads (Not Recommended for Heavy Traffic): A network of local roads (Routes 343, 345, and 347) provides a bypass, but these are not designed for high volumes of traffic and are likely to experience congestion. Use these only if absolutely necessary.
Public Transportation Options:
exo Trains: exo offers train service between Joliette and Montreal. This is a viable option for commuters. Check exo.quebec for schedules and availability.
Bus Services: Limited bus services operate in the area. Consult local transit authorities for details.
Carpooling: Consider carpooling with colleagues or friends to reduce the number of vehicles on detour routes.
Impact on Regional travel & Commerce
The Highway 40 shutdown is having a substantial impact on regional travel and commerce.
Commuting Delays: Commuters are facing significantly longer travel times, particularly those traveling between Berthierville, Lanoraie, and Montreal.
Freight Transportation: The closure is disrupting the movement of goods and services, potentially impacting businesses in the region. Trucking companies are rerouting their vehicles, adding to transportation costs.
Tourism: Tourist traffic to the Lanaudière region is expected to decline as travelers seek alternative destinations.
Local businesses: Businesses reliant on Highway 40 traffic may experience a decrease in customers.
