Ontario Begins Major Construction on Bradford Bypass

May 14, 2026

Province delivering on commitment to build key highway and reduce gridlock across York Region and Simcoe County

BRADFORD — The Ontario government has begun major construction on the Bradford Bypass, marking a significant milestone in the province’s plan to fight gridlock and shorten travel times across York Region and Simcoe County by up to 35 minutes. Construction of the new four-lane highway will support 2,200 jobs annually and contribute up to $286 million to Ontario’s GDP.

“With major construction underway on the Bradford Bypass, we’ve reached a historic milestone in our plan to give relief to commuters from some of the most congested highways in North America,” said Premier Doug Ford. “We will continue to invest in our $236 billion plan to build, including the Bradford Bypass, Highway 413 and the 401 tunnel, saving drivers and businesses across Ontario time and money.”

Crews have broken ground on the west section of the Bradford Bypass at Sideroad 10, where work is beginning to build the divided highway from west of Artesian Industrial Parkway to Highway 400. The work includes building interchanges at Sideroad 10 and County Road 4, replacing the bridge at Highway 400 and Line 9 and adding a new freeway-to-freeway interchange connecting the Bradford Bypass to Highway 400. Once complete, the 16.3-kilometre highway will run from Highway 400 in the west to Highway 404 in the east.

“Under the leadership of Premier Ford, our government continues to fight gridlock that costs Ontario up to $56 billion a year,” said Prabmeet Sarkaria, Minister of Transportation. “The Bradford Bypass will provide much-needed relief to drivers in York Region and Simcoe County, support thousands of good-paying jobs and keep people and goods moving in one of Ontario’s fastest-growing regions.”

The Ontario government is investing more than $31 billion to build, repair and expand highways, roads and bridges across the province. Last year, the province awarded contracts for the detail design of the central and east sections of the Bradford Bypass and named a program management consultant to oversee the full project.
