Dundas Street is a critical major east-west corridor with more than 40,000 daily road users. Since 2012, Halton Region has been making improvements to Dundas Street to accommodate growth in north Burlington and Oakville.

These improvements will address future traffic demands and provide safe travel options for motorists, pedestrians and cyclists and include:

Widening from four to six lanes
Road resurfacing
New multi-use paths and sidewalks
New bus stops and shelters
Upgraded stormwater management infrastructure
New traffic signals and street lights
New on-road bike lanes
Environmental protection measures
New bridges

Equipment for the Regional Advanced Traffic Management System (ATMS) will also be installed. The ATMS is a traffic signal control system that enables real-time signal adjustments to save time, reduce emissions and improve safety for motorists.

Improvements will be completed in three phases:

  • Phase 1:
    • Appleby Line to Tremaine Road (Contract 1: PR-2672B) – Anticipated construction start in Spring 2021
    • Tremaine Road to Bronte Road (Contract 2: PR-2671B) – Anticipated construction start in Spring 2022
  • Phase 2:
    • Appleby Line to Northampton Blvd. (PR-2550A) – Anticipated construction start in 2023
    • Northampton Blvd. to Guelph Line (PR-3200A) – Anticipated construction start in 2023
  • Phase 3:
    • Guelph Line to west of Kerns Road (PR-3207B) – Anticipated construction start in 2025

What you can expect day-to-day

Dundas Street is a major east-west corridor that many residents and motorists rely on to get to work, school, home and retail every day. Halton Region is making every effort to minimize the disruptions and help you plan ahead for construction activity the extension will create.

Learn more about what to expect day-to-day, our mitigation plans and how to stay connected on the project.

I’m a resident or business in the area

Advance notice of any service disruption or construction impacts will be provided to residents in-person, through letter, email and website updates.

Below are some impacts you may experience:

  • Night work: Night work is required as part of this project. We will provide advance notice of any change in work hours.
  • Dust and mud: There may be increased levels of dust and mud near the work site. The contractor is required to manage these impacts.
  • Noise: You may experience noise as a result of construction. We will schedule work in accordance with local noise by-laws.
  • Tree pruning and removals: Due to the road widening, certain trees will either be pruned or removed. This work may happen shortly to allow for the utility relocations to occur. New trees will be planted along the project corridor once construction has completed.
  • Truck traffic: You will notice increases in truck traffic around the ongoing work. Please be aware and use extra caution while driving.
  • Sidewalk access: There may be some sidewalk closures during construction. Pedestrian detour routes will be implemented.
  • Vibration: You may experience some vibration due to ongoing work. As a precaution, we recommend that you remove or secure objects on shelves and walls.

I use this road regularly

Advance notice of any closures or restrictions will be available through letter, email, social media, road signs and website updates.

The following mitigation strategies have been put in place to minimize the impact on traffic and travel:

  • Widening one side of the road at a time: This allows two lanes of traffic to continue in each direction.
  • Reducing speed limits: To ensure safety, the speed limit will be 60 km/h, and reduced to 50 km/h in some areas.
  • Using electronic road signs: Road signs will show up-to-date travel times.
  • Coordinating public transit: Halton will coordinate with Burlington Transit and Oakville Transit to ensure transit users have the latest information.

Bronte Creek restoration

In addition to the improvements to Dundas Street, Halton Region and Conservation Halton will be working together to restore the banks and valley wall of Bronte Creek, north of Dundas Street. The combination of the bank slope and the river movement have resulted in significant erosion of the valley wall of Bronte Creek.

This restoration will allow for native plant species to take root and contribute to long-term bank stabilization, and reduce the potential for continued failure of the slope. The native species will provide improvements for the Silver Shiner fish habitat by supplying nutrient inputs, adding channel diversity, providing nearshore cover and protecting habitats for endangered and at-risk wildlife, including bird and bat species.
