Ile aux Tourtes Bridge: Status, Closures & 2030 Rebuild

If you drive between Montreal and the Montérégie region, you’ve probably hit delays on the Île-aux-Tourtes Bridge more than once. The 2-kilometer span over Lake of Two Mountains has been a pinch point for decades, and now it’s in the middle of a major overhaul that won’t wrap until 2030.

Length: 2 km · Connects: Vaudreuil-Dorion to Senneville · Spans: Lake of Two Mountains · Avg Vehicles: 81,000 daily · Reconstruction End: 2030

Key details about the bridge’s official nomenclature, dimensions, and traffic patterns provide essential context for understanding its regional significance.

What is the Île-aux-Tourtes Bridge schedule?

The Île-aux-Tourtes Bridge carries Autoroute 40 across Lake of Two Mountains, connecting Senneville on the western tip of Montreal island to Vaudreuil-Dorion in Montérégie. The Quebec Government officially commissions the bridge in 1965, though construction ran from 1962 to 1965. Built as part of the Trans-Canada Highway, the span has long outlived its 35-year design life.

Upcoming closures

Planned maintenance closures have become routine. The Village de Senneville confirms complete closures in 2024, including a week-long shutdown March 12–18, 2024. Another full closure ran December 6–9, 2024, for lane reconfiguration, after which three lanes reopened including dynamic lane management. CityNews Montreal reported a closure for the weekend of October 3–6, 2025, with the westbound exit to Senneville Road closed from October 6 through December 2025.

Regular maintenance windows

The bridge has required repeated repairs since the 1990s: 1991–1992, 1994, 2000–2001, 2012–2013, and ongoing work from 2015 onward. By 2018, Quebec had spent $87 million on maintenance with an additional $45 million projected through 2028, according to Wikipedia. Shoring work began June 19, 2024, to stabilize the aging structure during the reconstruction phase.

The deconstruction of the current bridge is scheduled to wrap in 2029, with final work finishing in 2030, per the Quebec Government’s official project page.

Is the Île-aux-Tourtes Bridge closed this weekend?

Anyone planning weekend travel needs to verify current status before departing. The bridge has seen multiple emergency and scheduled closures over the past several years, and further weekend shutdowns are likely as reconstruction progresses.

Current closure status

Emergency closures have tested the bridge’s reliability. On May 20, 2021, an emergency shutdown followed discovery of damaged steel rods; the bridge reopened June 2, 2021. A more alarming incident occurred November 24, 2023, when a major crack prompted another emergency closure; traffic resumed November 27, 2023, with only one lane each direction. The most recent confirmed full closure ran October 3–6, 2025, reported by CityNews Montreal.

Recent closure reasons

Maintenance-related repairs drove most closures, while structural concerns triggered the emergency shutdowns. The 2021 closure traced to damaged steel rods; the 2023 incident involved a significant crack requiring engineering assessment before reopening. Planned closures since then have focused on lane reconfiguration and construction staging for the new structures. During closure periods, tolls are suspended on Autoroute 30 as an alternative route, and public transit is encouraged.

Is the Île-aux-Tourtes Bridge open today?

Checking the current status before you drive saves time and frustration. The bridge has operated under various lane configurations as work progresses, and real-time information is available through official channels.

How to verify openness

The Quebec Government’s transport page provides ongoing updates: Quebec Government official site. For real-time road conditions, the Quebec511 service at Quebec511 offers live status for Autoroute 40. As of April 28, 2025, four lanes total were restored: two toward Vaudreuil-Dorion, two toward Montreal, per available records.

Where is the Île-aux-Tourtes Bridge on the map?

The bridge sits at the western edge of Montreal island, spanning the Lake of Two Mountains that separates the island from the mainland. It’s part of Autoroute 40, making it a major corridor for commuters traveling between the island and the Montérégie region to the west.

Location details

The structure connects the municipality of Senneville on Montreal’s western tip to Vaudreuil-Dorion on the mainland. According to EXP Engineering, the bridge spans approximately 2 kilometers and crosses both Lake of Two Mountains and Île Girwood. The eight-span reinforced concrete girder structure has been carrying traffic since 1966.

Nearby routes

During closures, Autoroute 30 serves as the primary alternative, with tolls suspended on that route. The Senneville Road turntable remains closed at all times due to reconstruction, requiring drivers to use exit 41 for Senneville access post-October 6, 2025, per CityNews Montreal. The Vaudreuil-Hudson commuter rail line also offers a transit option that avoids bridge congestion entirely.

What is the latest Île-aux-Tourtes Bridge update?

The long-term reconstruction project is now well underway. Construction on the new structures began in fall 2023, with main construction activity starting December 12, 2023, according to the Village de Senneville.

Reconstruction progress

The Quebec Government projects the first new structure to open in late 2026 with five lanes under dynamic management. The second structure follows in 2027, permanently providing three lanes in each direction. This will replace the aging bridge, which was designed for a 35-year service life but has now operated for nearly 60 years.

Traffic impacts

With 81,000 vehicles crossing daily—including 11% trucks, based on 2023 data from the Quebec Government—disruptions affect a significant volume of commuters. The bridge handles an annual average of 21.9 million vehicles, according to ICRI. The rehabilitation from mid-2017 to August 2018 addressed deteriorating girders, but more fundamental reconstruction proved necessary.

Timeline signal

The bridge’s history reveals a pattern: repeated repairs eventually gave way to full reconstruction as the structure aged beyond its design life.

The timeline below captures the bridge’s major milestones from construction through the current overhaul phase.

The 2023 crack incident proved particularly alarming given the bridge’s age. Engineers from EXP Engineering, who handled rehabilitation work, warned that the prestressed concrete and reinforced concrete girders showed cumulative wear from weather and traffic overload.

What’s unclear

Several uncertainties remain as the project progresses.

• Exact current closure schedule: The Quebec Government provides project timelines but releases specific weekend closure schedules closer to each event. Motorists should check the official site for the latest notices.
• Live traffic conditions today: While Quebec511 offers real-time road status, detailed lane-by-lane availability information depends on active dynamic management implementation.
• Confirmation of 2026 opening: Given past delays on infrastructure projects of this scale, the late 2026 target for the first new structure carries some uncertainty, though government sources maintain this timeline.

Local businesses have felt the pinch during closures. “It’s terrible,” said Lucie Bourbonnais, owner of La Ribouldingue, a nearby establishment, in comments cited during one closure period. The economic impact on vendors who rely on bridge traffic remains an ongoing concern.

What experts say

EXP Engineering (engineering firm overseeing rehabilitation)

The first structure is scheduled to open in late 2026 with five lanes that will be dynamically managed according to traffic flow during peak periods.

Village de Senneville (local government authority)

Construction began December 12, 2023, with main construction activity intensifying as the project progresses toward the 2026 target opening.

Summary

The Île-aux-Tourtes Bridge has served Montreal commuters for nearly six decades, but its age has made frequent closures and emergency repairs the new normal. The Quebec Government’s $2.3 billion reconstruction project will eventually replace the span entirely, with new structures opening in 2026–2027 and full completion by 2030. For drivers, the choice is clear: bookmark Quebec511 for real-time status checks before every trip, plan weekend alternatives via Autoroute 30 during announced closures, and brace for continued disruptions until the new bridges take over. The 81,000 daily vehicles counting on this corridor will have better infrastructure eventually—but the transition period demands patience.
