Lane Closure on Colonel By Drive Begins April 27, 2026 – National Capital Commission Updates

On April 25, 2026, the National Capital Commission announced a single-lane closure on Colonel By Drive beginning April 27, 2026, as part of an ongoing wall rehabilitation project. The closure affects the eastbound lane from Rosedale Avenue to past the Bank Street bridge overpass and is scheduled to remain in place through July 2026. Traffic will alternate using automated signals on the remaining open lane.

The project, which involves structural repairs to retaining walls along the roadway, is expected to cause periodic disruptions for motorists but will maintain access for pedestrians and cyclists throughout most of the work zone. The National Capital Commission advises users to follow posted signage for any temporary multi-use pathway adjustments.

While the closure is a routine infrastructure update, it occurs amid broader transportation changes in the National Capital Region, including a separate 16-month detour plan for bridge work at Hog’s Back, which was also announced in April 2026. That project, reported by CBC, will require extended rerouting for vehicles and transit due to repairs on the Hog’s Back Bridge over the Rideau River.

Both projects are managed by federal agencies responsible for maintaining public infrastructure in Canada’s capital region. The National Capital Commission oversees parkways, green spaces, and commemorative sites, while Public Services and Procurement Canada typically handles bridge and highway structures under federal jurisdiction.

As of April 25, 2026, no further technological components, smart traffic systems, or digital monitoring tools have been publicly associated with the Colonel By Drive wall rehabilitation effort. The National Capital Commission has not indicated plans to integrate sensor-based monitoring or real-time traffic analytics into this specific phase of work.
