Latest News About Ligne Bleue Du Métro De Montréal

Here’s the latest on Montréal’s Ligne Bleue project as of 2025–2026.

• Overview of status: The extension toward the east is ongoing, adding multiple new stations and lengthening the line by several kilometers. Construction activity has been active in 2024–2025, with more work planned into 2026 and beyond. This aligns with official summaries that describe a multi-station extension and ongoing civil work.[1][4][6]
• Expected completion and opening: The STM’s shared timelines indicate a protracted schedule, with preliminary public openings anticipated around 2031 for the full extended line, with multiple new stations opening simultaneously to optimize operations. Previous communications also referenced a 2026–2031 horizon for different project milestones, though the exact opening date for all five new stations has been framed as contingent on completing key project milestones.[2][3][6]
• Key technical and construction details: The extension plan includes about 5 new stations over roughly 5.8–6 km, plus related infrastructure like a parking facility and a pedestrian tunnel linking to future bus rapid transit (SRB) lines. A major signaling upgrade (CBTC SelTrac) is in place or planned to modernize train control across the line, including the extended portion.[4][2]
• Current disruptions or service impacts: The project has involved street-level disruptions and detours near Jean-Talon Est and surrounding corridors, with anticipated bus detours and temporary traffic patterns as works advance. These disruptions have been tracked since 2024 and were planned to continue as construction expands.[3][9]
• Notable sources and milestones: The STM maintains a dedicated project page with updates and a FAQ that outlines expected completion windows and project scope, including five new stations and integration with the urban transit network. Thales is supplying the train control system as part of the modernization effort for the line, indicating a broader tech upgrade accompanying the physical extension.[6][1][4]

If you’d like, I can pull the most recent public notices from the STM’s project page and summarize any new milestones or updated timelines in a concise bullet list. I can also generate a simple visualization (e.g., timeline or map) showing major milestones and the sequence of construction phases. Please tell me which format you prefer.
