Montreal Transportation & Infrastructure Updates: What’s New in 2025

If you’ve lived in Montreal for more than a week, you know that the city’s relationship with its roads is… complicated. Between the legendary orange cones and the perpetual dance of detour signs, navigating the metropolis can feel like a sport. However, as we move through 2025, the city is shifting its focus from temporary patches to long-term structural evolution. From the expansion of the REM to the redesign of our most storied arteries, the landscape of how we move is changing.

The REM Expansion and the Transit Shift

The biggest talking point this year continues to be the Réseau express métropolitain (REM). While the initial branches have already altered the commute for thousands, 2025 marks a critical phase in integrating the system further into the urban fabric. We are seeing a concerted effort to improve the ‘last mile’ of the commute—the gap between the station and your front door. In neighbourhoods like Brossard and throughout the West Island, new bike-share hubs and revamped bus feeder lines are designed to reduce our reliance on the automobile.

Meanwhile, the STM is doubling down on the ‘bus priority’ initiative. By creating more dedicated lanes on congested stretches like Sherbrooke and Saint-Catherine, the city is attempting to make the bus a viable alternative to the Metro during peak hours. The goal is simple: make the transit experience predictable again, even when the snow starts piling up on the sidewalks of the Plateau.

Reimagining the Streetscape: Pedestrians First

Montreal has always been a city of neighbourhoods, but the 2025 infrastructure plan is pushing for more ‘human-centric’ zones. The trend of pedestrianization that peaked during the pandemic has now become permanent policy. We are seeing a significant expansion of the ‘ruelles vertes’ (green alleys) project, transforming hidden pathways in Rosemont-La Petite Patrie into lush, permeable corridors that combat the urban heat island effect.

Major overhauls are also hitting the downtown core. The city is investing heavily in the redesign of intersections around the Quartier des Spectacles to improve safety and flow. By widening sidewalks and adding protected bike lanes—specifically those connecting the Lachine Canal to the city centre—Montreal is signaling that the era of the car-dominant downtown is fading. For those navigating the narrow streets of Old Montreal, new paving projects are finally replacing crumbling cobblestones with materials that preserve the historic aesthetic while being accessible for wheelchairs and strollers.

The Bridge and Tunnel Bottleneck

Of course, it wouldn’t be a Montreal update without mentioning the bridges. The ongoing maintenance on the Champlain Bridge remains a priority, but the focus has shifted toward the long-term viability of the Jacques Cartier and Louis-H. Lafontaine crossings. Infrastructure updates in 2025 are leaning heavily into ‘smart’ traffic management. New sensor-based systems are being deployed to adjust signal timing in real-time, aiming to reduce the gridlock that typically paralyzes the entrance to the city during the evening rush.

While the orange cones may never truly disappear, the projects underway in 2025 are more than just repairs; they are a blueprint for a more sustainable, breathable city. Whether you’re gliding on the REM or strolling through a newly greened alley, the way we traverse Montreal is becoming more intuitive and less stressful.
