How Projects are Prioritized?
100 series highways
Decisions about major construction upgrades and twinning
of the 100-series highways are based mostly on traffic
volumes, safety studies, and collision statistics.
Decisions about 100-series paving projects since 2010
have been guided mostly by the department's Pavement
Management System. The system collects up-to-date
pavement conditions and traffic information on all 100-series
highways and uses a computer program to generate the
best possible maintenance and rehabilitation plan based
on nationally accepted guidelines.
This information with the technical knowledge of highway
program staff helps inform annual and multi-year paving
plans, including various rehabilitation and preservation
Trunks, routes and local paved
roads handling more than 500
There are many factors that we take into consideration when
assessing and making decisions about repaving secondary
and local paved roads:
- traffic volumes
- surface roughness
- pavement conditions (cracking, rutting, and
Priorities for pavement preservation projects, such as crack
and chip sealing, are developed by highway program staff,
who assess the current age and condition of the pavement.
Local low-volume paved roads
and gravel roads
The following factors help determine priorities for surface
- traffic volumes
- roadside development, including the number of homes,
businesses, and community sites (eg., churches,
community halls, recreation centres, parks, etc.)
located on the road
- requests for road repairs from residents, businesses,
not for profit groups, and community
- groups, chambers of commerce and elected officials
Provincial bridges are inspected and assessed regularly
by Department of Transportation and Infrastructure Renewal
engineers and inspectors.
Priorities for annual and multi-year bridge rehabilitation
and replacement programs are developed by staff, who
consider the condition, age, and use of the structure; the
volume of traffic and weights; and the class of roadway
where the structure is located.
Public safety is always the primary consideration.
