Most traffic impacts already in place as fall construction set to start


The City will be engaged in construction at more than 120 sites throughout Ottawa this autumn. This update was provided at today’s construction and mobility technical briefing. While 45 projects will start up this fall, a majority of the construction activity is now underway with traffic impacts already in place.


Heading into the fall, construction of the O-Train Confederation Line will continue to be the major focus. As a result, the shift of buses from the Transitway in the east onto the new bus-only lanes on Highway 417 and Ottawa Road 174 will still be among the biggest ongoing traffic and mobility impacts for residents.


OC Transpo reminds customers that all stations between Hurdman and Blair, except for Cyrville, remain open for service. On Sunday, September 6, the existing Hurdman Station platform will be replaced by a new platform just east of the current one. Customers who have not travelled on OC Transpo since June and who may not be familiar with the service adjustments that began at that time should visit to plan their trip before they travel.


LRT construction will continue to impact motorists on Nicholas Street between Highway 417 and Laurier Avenue. Traffic restrictions will also remain on Rideau Street between Sussex Drive and Dalhousie Street, related to construction of the Rideau Confederation Line station.


In late September the Ministry of Transportation Ontario (MTO) will also replace the Kent Street overpass on Highway 417, which will result in lane reductions and a weekend highway closure.


With all of the construction-related activities underway, residents are encouraged to be flexible with commuting times, stagger work hours or use alternative means for travel. The public is asked to consider options such as transit, walking and cycling.


The City of Ottawa has tools on to help motorists and transit users plan their routes and manage their commute including:
