Construction on Grand River Street North in Paris has been underway since the summer of 2023. This is a multi year infrastructure project focused on improving underground services, road safety, and long term mobility.

What's been done

Earlier phases of work replaced aging watermain and sanitary sewers between between Trillium Way and Hartley Avenue. These upgrades support current needs and planned growth in the area.

Where work will continue Current and upcoming construction will take place on Grand River Street North between Watts Pond Road and north of Silver Street.

Why it's needed This section of Grand River Street North is expected to see higher traffic volumes as the community grows. The work underway now prepares the corridor for the future while improving safety today.


What to expect

The project will:

  • Build four new roundabouts at Watts Pond Road, Hartley Avenue, Scott Avenue and Trillium Way to improve traffic flow. Roundabouts will have pedestrian controls similar to what was installed on Rest Acres Road last fall.
  • Install storm sewers to manage runoff and reduce flooding
  • Add a multi use path on the west side of the road and a sidewalk on the east side to support walking and cycling
  • Build on earlier watermain and sanitary sewer upgrades completed in previous years
  • New street lights to be installed
  • Road reconstruction including widening from two to four lanes of traffic

Traffic impacts

  • Two way traffic will be maintained in the north south direction
  • Temporary detours will be used during certain phases such as asphalt paving and work at side streets
  • Cross streets affected may include Scott Avenue, Woodslee Avenue, and Hartley Avenue
  • Clear signage will guide drivers, cyclists, and pedestrians

Safety and access for school, residents, and businesses

Special measures will be in place near Paris District High School to support safe walking routes for students. This includes temporary signage and protective mats where needed. Access to homes and businesses will also be maintained throughout construction with clear signage and detour routes available.

Important reminders

The County is working to reduce impacts where possible while keeping people moving safely. Please remember:

Businesses will remain open during construction. Please show your support and shop local.

    Construction on Grand River Street North in Paris has been underway since the summer of 2023. The work taking place includes the replacement of watermain and sanitary sewers from 100 metres south of Trillium Way to Hartley Avenue. This is a multi-year project to implement upgrades to Grand River Street North as recommended through the Grand River Street North Corridor Environmental Study Report and the Paris Master Servicing Plan.


    A reminder that during this construction, traffic will be managed by the following:

    • Grand River Street North will be reduced to one lane, one way in the southbound direction only.
    • All northbound traffic will be detoured along Silver Street, Oak Avenue and Scott Avenue.
    • Intersections and driveways will be open but will require one-to-two-day closures from time to time throughout the work.
    • All businesses will remain open during construction.


    Additional safety measures have also been implemented along the detour routes including speed humps, speed display signage, and a temporary school crosswalk on Oak Avenue at Whitlaw Way. Residents are reminded to please obey all signage.

    Please refer to Municipal 511 for the most up-to-date traffic information regarding road construction and closures.

    Future phases of the work will include the widening of Grand River Street North along with replacement of curbs and sidewalk and the installation of roundabouts at intersection locations. Work in 2024 will include the installation of a roundabout at Scott Avenue and continuing north toward Hartley Avenue as well as the reconstruction of the signalized intersection at Silver Street and extension of a new street from that intersection to the east. Future works are subject to budget approval and further notice of these works will be provided once approved.
