Process details

The Town is responsible for the design and construction of all municipal roads, bridges and culverts. The process may require two or more years.
  1. Surveying is conducted
  2. An informal Project Initiation Meeting is held for new projects, with stakeholders, at the start of the design process
  3. Design work continues, including modifications from initial public feedback
  4. Public Input - A formal Public Information Centre is held later in the design process to present detailed design(s) to the community, at which time input is also requested
  5. The final design is presented to Council for approval
  6. Design projects generally begin in the spring and are completed in the late fall or early winter
  7. Construction projects are typically tendered in the winter and early spring
  8. Work generally commences in mid to late spring
  9. Construction timing, particularly in or near waterways, may be constrained by environmental requirements
  10. Every effort is made to minimize disruption to abutting properties during construction

Due to the scope or scale of any individual project, timelines and steps may vary. For example, not all projects will include a Project Initiation Meeting or Public Information Centre.

Environmental assessments

The Town currently has one ongoing Schedule C Municipal Class Environmental Assessment, the Boyne Active Transportation Link.  

An environmental assessment first step in all of our capital road projects. The project schedule (or type) according to the Municipal Class Environmental Assessment (MCEA) process is determined.

The MCEA has five phases:

  1. Identify the problem or opportunity
  2. Identify alternative solutions and evaluate them
  3. Prepare and evaluate alternative design concepts for the preferred solution
  4. Prepare an environmental study report
  5. Implementation (complete detailed design and ultimately proceed to construction)


The Canada Community-Building Fund is money the federal government gives to municipalities twice a year to support local infrastructure.

Local road construction projects partly funded by the Canada Community-Building Fund include:

  • Asphalt overlay of multiple streets
  • First Line, Lawson Road, and No. 5 Side Road resurfacing
  • Victoria Street (Bronte to James Street) reconstruction
  • Lower Base Line and Sixth Line resurfacing
  • Bronte Street (Main Street to Steeles Avenue) redevelopment
  • Bridge and culvert rehabilitation
  • Fifth Line urbanization
  • Asphalt overlay of multiple streets
  • Campbell Avenue (east of Guelph Line) reconstruction

Road construction definitions

Asphalt overlay 

The process of replacing existing deteriorated asphalt surfaces with new. It also involves replacing portions of curb and rebuilding catch basins and manholes.

Expanded asphalt

Rehabilitation (usually limited to rural or industrial roads) of the road structure, which may include removal of asphalt, pulverizing of asphalt and granular material, and repaving with new asphalt, or utilizing asphalt recycling methods, depending on the particular road.  Also includes the installation of paved shoulders where feasible, and minor/localized ditch work and cross culvert replacements or repair.

Reconstruction and improvements 

The process of reconstructing an existing substandard road to current standards.


The process of completely rebuilding a road. This includes all the underground infrastructure and replacement of the road structure.

Surface treatment 

Surface treatment is the application of an asphalt based emulsion binder and a granular based wearing surface. The process waterproofs the roadway and eliminates grading and dusting of gravel rural roads.


Urbanization is the improvement of a road with ditches to a road with curb and gutter, drained by storm sewers.
