Highway 425 Construction Closes Line 9 Near Highway 400 in Bradford West Gwillimbury
If you travel between Barrie, Innisfil, Bradford West Gwillimbury and Highway 400, this is a construction project to keep on your radar.
As work continues on the future Highway 425, also known as the Bradford Bypass, a section of Line 9 between Sideroad 5 and Sideroad 10 in Bradford West Gwillimbury is expected to be closed to through traffic for approximately three years.
For commuters, residents and anyone considering a move in south Simcoe County, this project may affect travel routes, daily timing and long-term access across the region.
Which Part of Line 9 Is Closed?
The closure affects Line 9 between Sideroad 5 and Sideroad 10 in Bradford West Gwillimbury.
Through traffic is being detoured to County Road 88. Local access for residents living on Line 9 is expected to be maintained, and Henderson Memorial Community Park is expected to remain accessible by using Sideroad 10 and Line 9.
Why Is Line 9 Closed?
The closure allows multiple construction activities to happen at the same time while major work takes place on the western section of Highway 425.
This work includes building new interchanges, replacing bridges, creating temporary structures, relocating utilities and moving large construction equipment through the construction zone.
In simple terms, keeping Line 9 open to regular through traffic would make the work slower and less safe.
What Is Highway 425?
Highway 425, commonly referred to as the Bradford Bypass, is a planned controlled-access highway that will connect Highway 400 and Highway 404.
The planned highway is expected to be approximately 16.3 kilometres long, with four lanes to start and the ability to expand in the future. It is also planned to include future high-occupancy vehicle lane potential, new interchanges and active transportation connections in certain areas.
What Drivers Should Expect
For the next several years, drivers should expect detours, construction traffic and longer travel times in parts of Bradford West Gwillimbury and south Simcoe County.
Anyone travelling through this area should allow extra time, follow posted detour signs and watch for future notices about temporary Highway 400 closures related to the project.
