College Street Underpass and Ste. Anne Road Extension

The College Street Underpass (also known as the CPR Subway) is a 2-span concrete bridge constructed in 1949 to accommodate 3 lanes of traffic crossing under the CPR railroad tracks. Currently, there is a sidewalk on the west side of the structure and no other active transportation facilities. Given the age and condition of the structure, the low vertical profile and the lack of active transportation facilities, the structure needs to be replaced, or at a minimum rehabilitated.

Ste. Anne Road located in downtown Sudbury between Notre Dame Avenue and Mackenzie Street is a 4-lane arterial road. The City of Greater Sudbury Transportation Master Plan (2017) identified the need to extend Ste. Anne Road to Frood Road to alleviate traffic pressures in the area.

The concurrent completion of both projects will assist in ensuring the vertical and horizontal alignments of the new Ste. Anne Road extension and the College Street underpass are compatible.

The City of Greater Sudbury through their consultant AECOM, has initiated a Municipal Class Environmental Assessment (MCEA) study to identify, evaluate and determine the best long-term rehabilitation or replacement alternatives for the College Street Underpass and the best alignment for the Ste. Anne Road extension.

The Process

The study will be completed in keeping with the Ontario Environmental Assessment Act and will follow the MCEA Schedule C requirements (Master Plan Approach #3) of the Municipal Engineer’s Association MCEA manual (2023). This is considered a Schedule ‘C’ project which typical includes the construction of new facilities or major expansions to existing facilities with significant environmental impacts. Consultation with the public is mandatory.
