Traffic impacts in Ottawa as a result of upcoming road work

September 28, 2017
Announcements and Events

Upcoming road work projects will have the following impacts on Ottawa traffic:

  • West Transitway extension project – Due to the diversion of traffic onto the newly constructed bridge of the West Transitway extension, the existing westbound 417 off-ramp at Moodie Drive will be closed to vehicular traffic from 11 p.m., Friday, September 29 until 5 a.m., Monday, October 2. Detour signs will be in place to direct motorists around the closure.
  • O-Train Trillium Line – OC Transpo’s O-Train Trillium Line service will be temporarily replaced by Route 107 bus service from 7:30 a.m. until 1 p.m. on three upcoming Sundays on October 1, 15 and 22. These temporary closures will allow for site inspections in preparation for future service expansion.
    Route 107 buses will travel parallel to the Trillium Line routing between Bayview and South Keys stations every 15 minutes, with limited stops along the way to provide service in proximity to the Trillium Line stations. In addition to Route 107, there may be other bus route options that work better for some customers. For schedules and travel planning assistance, visit or call 613-741-4390.
  • Greenfield Avenue and Main Street – Greenfield Avenue between Main Street and Havelock Street, as well as the intersection of Greenfield Avenue and Main Street, will be reduced to one lane in each direction during off-peak periods due to road resurfacing. In addition, Main Street at Oblate Avenue and Springhurst Avenue will be reduced to one lane in each direction during off-peak periods for construction work. The work is beginning Monday, October 2 and will continue until the end of October. Flagging operations will be in effect to control off-peak traffic as necessary. Motorists can expect delays through the construction zone.
  • Rideau Road – 0.05 km west of Ramsayville Road will be closed from Monday, October 2 to Friday, October 6 for a culvert replacement.

Signed detours will be in place to direct motorists around the closures. For more updates on the construction and road work activity across the city, or for information about traffic and travel planning, visit the City’s Traffic Report on or follow the City’s traffic account on Twitter.
