Municipal Class Environmental Assessment Studies

To consider a range of options for corridor improvements on:

• James Snow Parkway from Britannia Road to Highway 401 (Milton)
• Steeles Avenue from Regional Road 25 to Trafalgar Road (Milton/Halton Hills)
• Regional Road 25 from 5 Side Road to 10 Side Road (Halton Hills)

Halton Region will examine a wide range of multi-modal transportation improvements, including roadway widening, cross-sectional requirements, active transportation, transit supportive infrastructure, intersection improvements and overall traffic operations, as well as the impact of such improvements on the social, cultural and natural environments.
