Municipal Class Environmental Assessment Studies
James Snow Parkway Extension MCEA Addendum
Details
Purpose
Halton Region is undertaking an Addendum to the Municipal Class Environmental Assessment (MCEA) study completed in 1999 for James Snow Parkway from Highway 401 to Neyagawa Boulevard (including a new bridge crossing over East Sixteen Mile Creek).
Since the 1999 study, the section of James Snow Parkway north of Britannia Road has been constructed and is now a Regional Road. Halton Region’s Transportation Master Plan to 2031 identified the James Snow Parkway extension from Britannia Road to Highway 407 Express Toll Route (ETR) as a six-lane corridor. This Addendum is to address updates to road design and related considerations, including a change from a 35-metre rural, four-lane roadway to a 47-metre six-lane urban right-of-way. The Addendum will also update mitigation measures to align with current legislation and policies.
Scope
Through this MCEA study addendum, the project team will consider the following road design considerations:
- A six-lane corridor
- Active transportation facilities
- Provision for existing and future intersections
- Protection for future transit priority corridor infrastructure
- Crossing over East Sixteen Mile Creek
