Major roads in downtown Ottawa will close this Saturday and Sunday to accommodate the Ottawa Race Weekend and local community events [1].

These closures affect primary arterial roads and the areas surrounding Ottawa City Hall, potentially disrupting transit and vehicle traffic for thousands of residents and visitors. The coordination between city officials and event organizers aims to ensure safety for participants and pedestrians during the high-traffic window.

The road closures are scheduled from Saturday, May 23, to Sunday, May 24, 2026 [3]. Impacted areas include the streets around 110 Laurier Avenue West, where Ottawa City Hall is located [3].

In addition to the athletic events, the city is preparing for the 40th edition of the Great Glebe Garage Sale [1]. This milestone anniversary event coincides with the race schedule, adding further pressure to the traffic flow in the Glebe neighborhood and surrounding downtown corridors [1].

Organizers and the City of Ottawa have coordinated these restrictions to manage the influx of people into the city center [1]. Motorists are advised to seek alternative routes or use public transit to avoid the affected zones throughout the weekend [3].

Major roads in downtown Ottawa will close this Saturday and Sunday

The overlap of a major athletic event and a milestone community sale creates a significant logistical challenge for downtown Ottawa. By closing arterial roads, the city prioritizes pedestrian safety and event viability over vehicle throughput, which typically leads to increased congestion on the periphery of the restricted zones.
