The Government of Ontario has begun major construction on the Bradford Bypass—to be designated as Highway 425—with the awarding of the contract for the west section to The Miller Group.
“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.
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.
“Breaking ground on the west section of the Bradford Bypass is a significant milestone for our community and our region. As Bradford West Gwillimbury continues to grow, investments like these are essential to reducing congestion, improving travel times and supporting economic opportunity. We thank the province for their continued partnership and commitment to building stronger connections between communities,” said James Leduc, Mayor, Bradford West Gwillimbury.
Last year, the province awarded contracts for the detail design of the central and east sections of the Bradford Bypass to WSP Canada Inc. and Stantec Consulting Ltd., and named Jacobs Consultancy Canada Inc. and Egis Canada Ltd. as program management consultants to oversee the full project.
