Share on Facebook Share on Twitter Share on Linkedin Email this link

The City of Greater Sudbury is widening Municipal Road 35 (MR35) from Notre Dame Street East, Azilda to Highway 144, Chelmsford. The new roadway will include road widening to four lanes from Notre Dame East to Notre Dame West and to five lanes from Notre Dame West to Highway 144 (including a continued shared centre turn lane). In addition, the new roadway will include intersection improvements, traffic signal upgrades, paved shoulders with rumble strips, drainage improvements, new signage, pavement markings and guide rails, where required. Approximately 975 metres of water main upgrades will also be undertaken near the Chelmsford section of this corridor.

Project Background

MR35 is an important gateway to the community of Greater Sudbury. MR35 is an arterial road that connects the communities of Azilda, Chelmsford, Dowling, Levack, and Onaping to the downtown. The widening of MR35 to install additional driving lanes was recommended in the Sudbury Regional Transportation Study (March 1992), and reaffirmed in the 2005 Transportation Master Plan Study and the 2015 Transportation Master Plan Study for the City of Greater Sudbury.

Project Construction

Construction of MR35 began in the fall of 2018 with a culvert replacement contract.

In 2019, MR35 was widened from two (2) to four (4) lanes from Notre Dame Street East (Azilda) to Notre Dame Street West (Azilda). Intersection and drainage improvements were also completed along this section of MR35. Final layer of asphalt and restoration work to be completed in the Spring of 2020.

In 2020, construction is planned for the widening and infrastructure improvements along MR35 from Notre Dame Street West (Azilda) to Highway 144 (Chelmsford).

Thank you for bringing these points forward. Although the MR35 project focuses on the increase in vehicle lanes from two (2) to four (4), it also includes a two (2) metre paved shoulder for cyclists and has improved pedestrian crossings at signalized intersection. The City of Greater Sudbury supports active transportation as a viable alternative to private automobile for short-distance trips and for promoting a more active and healthy lifestyle. The City is actively involved in community projects that focus on addressing the environment. In May 2019, Council declared a Climate Emergency and the City is currently investing in a community-wide project to create Sudbury's local clean energy future - "Power Now: Energy and Emissions Plan."

Rather than increasing capacity for vehicles, please consider ways of reducing personal and commercial vehicle use. Increase transit, incentivize carpooling, increase safe active transport routes.example, Incentives and tax breaks could be provided to those who drive under 5,000km a year.

why do we keep doing the same things over and over and over -each time expecting different results? ( Einstein said this was the definition of insanity)

Why is it being done in two stages traffic could be rerouted.

Hi Paula, thank you for your question.. MR35 is an arterial road and was designed to Ontario provincial standards and specifications and the City would not use unapproved material.

LID permeable paving products are good for 25 years and will help to prevent flooding ( doesn't get potholes either). Will you consider using it as they now do in Europe and in King City Ontario.
