Investing in highway infrastructure
We invest billions of dollars every year to expand and improve the provincial highway network, creating jobs and connecting people and places across Ontario.
Ontario’s highway programs include every expansion and rehabilitation project underway or planned for the next four years.
Learn about Ontario’s priority highway expansion projects in our regional transportation plans:
- Northern transportation plan
- Southwestern transportation plan
- Greater Golden Horseshoe transportation plan
We maintain 16,900 kilometres of provincial highways and about 2,800 bridges year-round.
We oversee winter maintenance work completed in 26 contract areas across the province. Learn more about how highways are cleared in winter.
We are a leader in North America in bridge safety and our laws require frequent and detailed inspections. Each of Ontario’s 2,800 provincial-owned bridges undergo general maintenance inspections at least twice a year and detailed inspections every two years.
Inspectors are trained engineers and technicians who rigorously examine each bridge to ensure they remain safe for travel.
Every year, municipalities can apply for provincial funding to repair designated roads and bridges that connect two ends of a provincial highway through a community or to a border crossing.
The Connecting Links program funds up to 90% of eligible project costs, to a maximum of:
- $3 million for road projects
- $5 million for bridge projects
Apply for funding online through the Transfer Payment Ontario portal.
