Maley Drive Extension: Building Today for a Better Tomorrow

Heavy traffic sharing the road with ore and slurry haul trucks on LaSalle Boulevard

The Community Consultation process is now closed. The City thanks those who contributed to the consultation process. Written submissions received up to 4 p.m. on March 18 (end of public input period) are available in the agenda of the Public Input and Information Session from March 1. Written submissions received by the City are attached to the agenda in three files: items 1.11, 1.12, and 1.13.


The Maley Drive Extension is a solid investment in the social, economic and environmental future of the City of Greater Sudbury that will deliver short-term, medium-term and long-term benefits to residents, business and industry in an affordable and fiscally responsible manner, made possible by a three-way cost sharing partnership.



The Maley Drive Extension will be built in two phases. Phase One will connect LaSalle Boulevard West with Falconbridge Highway.

  • A new four-lane road will be constructed from LaSalle Boulevard West, near Collège Boréal, to Barry Downe Road.
  • Traffic will access the new four-lane road via a new interchange to be constructed north of LaSalle Boulevard on Notre Dame Avenue (Municipal Road 80).
  • To accommodate the new interchange, Notre Dame Avenue will be widened from four lanes to six lanes, north of the improvements that have already been made to the LaSalle-Notre Dame intersection and approaching lanes.
  • Traffic control at new intersections created by the construction of the four-lane Maley Drive Extension will be achieved with roundabouts at Collège Boréal and Barry Downe Road.
  • An existing section of Maley Drive, between Barry Downe Road and Falconbridge Highway, will be rehabilitated to complete Phase One of this project.

The total construction cost of Phase One of the Maley Drive Extension is $80.1 million.

Phase Two will extend the Maley Drive Extension to Elm Street West (Municipal Road 35).

  • The existing LaSalle Extension will be widened from two to four lanes between Collège Boréal and Municipal Road 35 (Elm Street West), connecting with the new four lane Maley Drive for improved traffic flow and safety.
  • The rehabilitated section of Maley Drive will be widened from two to four lanes between Barry Downe Road and Falconbridge Highway.
  • An existing railway crossing on Maley Drive, west of Falconbridge Highway, will be reconstructed as an overhead crossing for the safety and convenience of motorists.
  • Roundabouts will be constructed for traffic control on Maley Drive at the intersection of Lansing Avenue and at the intersection of Montrose Avenue. The Montrose Avenue roundabout will connect with a road design through a private subdivision that will eventually extend Montrose north to intersect with Maley.

The total construction cost of Phase Two of the Maley Drive Extension is currently estimated at $70 million.

The Maley Drive Extension addresses the future needs of the City of Greater Sudbury.

The City of Greater Sudbury Official Plan has identified the Maley Drive Extension as the number one priority for municipal infrastructure development. The Plan envisions a perimeter highway-arterial road system around the City of Greater Sudbury for efficient routing of traffic through this part of the region and province.

  • Phases One and Two of the Maley Drive Extension are the first steps to a perimeter highway that will extend Maley Drive east of its current end at Falconbridge Highway, southeast to connect to Highway 17 East to North Bay and Ottawa and an existing by-pass leading to Highway 69 South to Toronto and Highway 17 West to Sault Ste. Marie.
