Road Work Ahead

The following areas are scheduled for or are currently undergoing road and other major infrastructure work that is expected to affect traffic.

Sewer & Watermain Work

  • Cumberland Street between Stephens Street and Gibson Avenue is scheduled for road reconstruction including replacement of the watermain, new storm sewer, street lighting improvements and landscaping work. The project is currently underway and will continue until the end of October 2016. Work on this street will proceed in stages. Stage 1, currently underway, extends from Stephens Street to Clavet Street. Traffic is permitted in one lane only heading southbound on Cumberland Street within the staged limits. Northbound traffic is required to follow the posted detour route.
  • Storm sewer construction on Brunswick Street between Waterloo Street and Cumming Street is expected to proceed. Watch for road closures with local traffic access only as work proceeds.
  • Robertson Street from Pacific Avenue to Simpson Street is slated for road reconstruction including new sewers and watermains. Sections of sidewalks will be replaced as well. The road will be open to local traffic, but closed during some of the deeper excavation work.
  • The Boulevard Lake parking lot on Lyon Boulevard West as well as Algoma Street between Gibson Street and MacDougall Street are under construction for the installation of twin large diameter feeder watermains. The work will limit traffic in the area and will be completed by late June.
  • Watermain lining work will be completed in the area bound by Victoria Avenue, Franklin Street, Arthur Street and Brunswick Street. Open pits will be excavated and fenced off for safety. Construction crews will occupy the area over a six week period. While local traffic will not be impacted, motorists are advised to avoid the area if possible.
  • Top lift paving and final landscaping will be completed throughout the month of May on Ironwood Street between Edward Street and Sherbrooke Street.
  • Improvements to Banning Street between Bay Street and Pearl Street include sewer and watermain replacements, new curb and gutter, and road reconstruction. This project will take 10 to 12 weeks starting in late May. Only local traffic will have access to the area.
  • Sewer and water construction will start on Gore Street West from Neebing Avenue to Crawford Avenue the week of May 9. Drivers can expect block to block closures for through traffic with local traffic access only.

Bridge Work

  • Inspections of all the City's bridges will take place throughout the summer season. Expect occasional lane closures on the various structures throughout the City.

Road, Street Lighting & Sidewalk Improvements

  • Road rehabilitation work is underway on Balsam Street starting at Wardrope Avenue and extending 140 metres north of Lancaster Avenue. Watch for lane and road closures as the work proceeds.
  • Road resurfacing work on Shipley Street between Margaret Street and Huron Avenue is expected to commence shortly. Watch for road closures as the work proceeds.
  • Residential resurfacing work is slated to begin on Elliot Street and Bailey Avenue.
  • Asphalt patching work is scheduled to start on sections of Court Street, Hodder Avenue, Shipyard Road, Arthur Street, Memorial Avenue, and Southern Avenue. Watch for road and lane closures as the work proceeds.
  • Balmoral Street reconstruction between the Neebing McIntyre Floodway and Hewitson Street will commence May 24. Work will include new pavement, curb and gutter, and storm sewers, and the existing ditches will be filled. New multi-use trails will also be constructed on both sides of the road. During construction traffic will be restricted to one lane in each direction.
  • Widening and road resurfacing work will commence on Hemlock Place/Avenue. Only local traffic will have access to the area.
  • Road rehabilitation work on Vickers Street between Victoria Avenue and Cameron Street is expected to start. Watch for block to block road closures with local traffic access only as the work proceeds.
  • Civilwork construction for new traffic signals will occur at the Carrick Street and Central Avenue intersection. Some lane closures during working hours may result. New signal installation will occur later in the season.
  • Sidewalk work on sections of Fort William Road, Oliver Road and McIntyre Street may result in possible lane closures.

The above list includes major, traffic-affecting construction. Other work, including sidewalk replacements and curb and gutter repairs, is scheduled for residential areas and other areas around the City. The schedule is subject to change.


Each spring, once the snow is gone, street sweeping on arterial and collector roads begins.

Depending on weather, work on arterial and garbage collection routes is completed near the end of May.

Crews move onto arterial routes in downtown areas in early May.

Line of Street SweepersThe cleaning process takes six to eight weeks. Once arterial routes are complete, sweeping efforts move on to residential streets. Sidewalks are swept along with the streets as crews move through the City. For fairness, each year the schedule for sweeping in residential areas is rotated. The City is divided into areas and it takes approximately six weeks to complete the sweeping of residential areas.

The City also repairs areas of sod that are turned up adjoining the curb in the course of winter roads maintenance. We welcome your input if you notice areas of concern. Inquiries may be sent to

Residential Street SWEEPING priority map

City residential areas will be cleaned in numerical order. The order in which residential areas are cleaned by City crews changes each year - the first neighbourhood this year will move to the bottom of next year's list, and all other areas will move up.
