Britannia Road Corridor Improvements


Britannia Road is a critical east-west corridor in Halton Region that motorists rely on to get to work, school, retail and home every day. To accommodate growth, provide safe alternative transit options and improve traffic flow, Halton Region is planning to make improvements to Britannia Road.

With construction starting in summer 2019, Britannia Road (from Tremaine Road to Highway 407) will be widened from 2 to 6 lanes and upgraded to include bike lanes, traffic signals and streetlights. The Britannia Road improvements will be completed in three phases:

  • Phase 1 - Tremaine Road to Regional Road 25 (Project #2667): Starting summer 2019
  • Phase 2 - James Snow Parkway to Highway 407 (Project #2668/2669): Starting fall 2019
  • Phase 3 - Regional Road 25 to James Snow Parkway (Project #2670): Starting spring 2020

Project Updates

Public Information Centre:
Halton Region is holding a Public Information Centre on Tuesday, April 9, 2019 from 6:30 to 8:30 p.m. at
Craig Kielburger Secondary School (Cafeteria) – 1151 Ferguson Drive, Milton.

Traffic Updates:
When construction begins, home and business owners will be given advanced notice of any traffic impacts. To avoid the need for full road closures, motorists will be able to use the existing road while new lanes are built. Throughout the project, mitigation plans will be in place to keep traffic moving and provide motorists with safe alternatives.

There are no planned detours at this time.

Resident Impact:

  • 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 & 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 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.
