What's happening with the Greenbank Road realignment?
Phase 1 construction of the Greenbank Road realignment began in 2026 — a new four-lane arterial road with pedestrian and cycling paths, running from about 200 metres south of Cambrian Road north to Riverboat Heights. Through the build, expect lane reductions, alternating traffic, and detours along the corridor.
What the project is
The realignment reshapes one of Barrhaven's busiest north–south routes. Phase 1 is building a new four-lane arterial with sidewalks and cycling facilities between Cambrian Road and Riverboat Heights. The work is part of the City of Ottawa's Greenbank Road Realignment and Southwest Transitway Extension project, and the City added about $56 million to it in the 2026 budget.
How it affects your commute
Drivers should plan for staging, lane reductions, and signed detours along Greenbank through construction. The City publishes specific road closures as they happen — for example, short local-access-only closures on side streets near the work zone. Barrhaven Bugle posts each closure as the City announces it in the local news feed and the weekly newsletter, so check before a detour catches you out.
