Frequently Asked Questions
What are the benefits of this project?
The widened Dufferin Street corridor will provide additional capacity for York Region travellers. The 3-metre wide multi-use path on both sides of Dufferin Street will support pedestrians and cyclists.
Are there lane closures or reductions associated with this project?
- Off-peak lane reductions may be required between 9:30 a.m. and 3:30 p.m.
- Traffic will be directed during lane reductions
Will there be any night work?
Crews will be working extended working hours until 9 p.m. on weekdays, until mid-April 2023
Can pedestrians and cyclists still use Dufferin Street?
- Every effort will be made to maintain areas for pedestrians and cyclists. However, due to the nature of the improvement project and limited space, some areas may require added caution and awareness while travelling.
- Lane closures may be required to complete specific construction, limiting pedestrian and cyclist access during this time. Signage, detour information and notifications will be provided as required.
How is the natural environment considered during construction:
Trees on the west side of Dufferin Street south of Rutherford Road will need to be removed, in accordance with the design, as their roots will be impacted by construction. At the end of construction, the trees will be replaced.
York Region only removes trees if absolutely necessary. Each year, York Region plants thousands of trees and maintains Regional forests to offset the removal of trees during construction projects.
Why are these improvements taking place?
- York Regional Council continues to invest and make transportation improvements a priority, outlined in the 10-year Roads and Transit Capital Construction Program
- Roads are identified for improvements for a variety of reasons including enhancing safety for pedestrians and cyclists, managing assets in a state of good repair and improving traffic flow to accommodate population growth by adding new lanes or creating new roads
- To support the growing communities in Vaughan, construction is planned for over 20 locations in the next five years. These projects will include:
- Road reconstruction and widening
- New transit terminal connecting to the new Cortellucci Vaughan Hospital
- Intersection upgrades and improvements to enhance traffic operations
- Pavement repair, preservation and rehabilitation
- As York Region’s population and businesses grow, public roads are accommodating more travellers, goods and services
- Vaughan’s population is forecasted to grow from 316,000 in 2016 to 497,400 by 2041
- Vaughan’s employment is forecasted to grow from 209,200 jobs in 2016 to 321,500 jobs by 2041
- The travel growth in the area (daily trips to and from Vaughan) is forecasted to grow from 895,400 in 2016 to 1,315,700 by 2041, an 47% increase
- By expanding or upgrading infrastructure, we are ensuring we meet the needs of our growing communities now, rather than waiting until we run out of capacity
Why is this construction happening all at once?
- York Region has a 10-year Roads and Transit Capital Construction Program which outlines infrastructure projects across the Region. Capital projects are undertaken to improve the community for all York Region residents
- While serving growth remains important, capital spending also focuses on asset management to extend the life of assets, such as roads and bridges, and reduce total costs over their life cycle. Over the next 10 years, $1.4 billion will go to rehabilitating and replacing existing assets. These investments help ensure that assets are in a state of good repair for current and future residents
- The Region and the City of Vaughan are investing in transportation improvements over the next five years to support the record growth in the area, the construction being completed by our partners and to maintain our roads in a state of good repair
- Infrastructure being constructed by the Region and our partners includes:
- Road widening and York Region Transit (YRT) bus terminal construction on Major Mackenzie Drive, from Highway 400 to Jane Street, with a direct benefit to the newly constructed Cortellucci Vaughan Hospital
- Installation of water, wastewater and telecom infrastructure and planting street trees as part of road construction projects
- Infrastructure being constructed by the Region and our partners includes:
- The Region is addressing the growing needs of City of Vaughan residents, businesses and the travelling public, as traffic congestion is identified as the number one public concern in Vaughan
- To maximize as much work as possible, the majority of construction projects are completed in the warmer months when the ground is not frozen and temperatures for mixing and laying asphalt is ideal and traffic volumes are lower
Does York Region coordinate with other projects happening in the area?
Whenever possible, York Region coordinates with the City of Vaughan, developers, utility companies, Environmental Services and other agency infrastructure programs, including the Ministry of Transportation of Ontario (MTO), Metrolinx, rail authorities, York Region Rapid Transit Corporation and York Telecom Network (YTN), when planning construction projects within the Region. Effective coordination may result in financial benefits and can help minimize impacting the public multiple times and reducing disruption to travellers
Due to the complexity and timing requirements of certain projects, it is sometimes not possible to avoid construction on adjacent or parallel roads
How are residents impacted by the project being informed?
- To help travellers plan ahead during road construction, we install advance signage, post messages on social media and our website, and distribute notices
- Travellers are encouraged to use traffic and navigation tools. York Region provides real-time traffic and road information in open data, used by many apps
