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 rehabilitated or replaced.

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 typically includes the construction of new facilities or major expansions to existing facilities with significant environmental impacts. Consultation with the public is mandatory.

Current Status of Project

The Environmental Study Report for this project was issued on June 24, 2024 with the question period ending July 24, 2024. All questions submitted are currently being responded to. After all comments have been responded to, the detail design portion of this project will commence. This design work will include the rehabilitation of the College St. Underpass and improvements to College Street, College/Frood intersection and the proposed roadway for the Ste. Anne Road extension.

Construction for the improvements to the College St. Underpass, College Street and the College/Frood intersection is tentatively scheduled to begin in 2025 pending necessary approvals and funding.
