The Bradford Bypass is one of the most significant infrastructure investments in East Gwillimbury's history, and most Buyers haven't fully factored it into their decision-making yet. Here's the plain-English version: what it is, where construction actually stands in 2026, and what it means if you're buying nearby.
What Is the Bradford Bypass?
The Bradford Bypass, now officially designated Highway 425, is a 16.3 km freeway-standard highway connecting Highway 400 in Bradford West Gwillimbury to Highway 404 in East Gwillimbury. The project was in planning for decades, and construction is now under way: Ontario awarded the western-section contract in May 2026 and crews have broken ground at the Bradford (Highway 400) end, while the central and eastern sections through East Gwillimbury remain in detailed design.
By the numbers: now Highway 425 · more than $1B estimated cost (Infrastructure Ontario) · 16.3 km route · connects Hwy 400 to Hwy 404 · passes through northern East Gwillimbury · west-section construction began May 2026; central and east sections in design
2026 Construction Update: What's Happening Now
Here's where the project actually stands as of mid-2026, because "under construction" and "coming to my area" aren't the same thing. Ontario began major construction on the west section in May 2026, with The Miller Group awarded the build. Crews broke ground at Sideroad 10 and are building the divided highway toward Highway 400, including a new freeway-to-freeway interchange at the 400 and interchanges at Sideroad 10 and County Road 4.
Status, mid-2026: west section under construction since May 2026 (contractor: The Miller Group) · groundbreaking at Sideroad 10, building toward Highway 400 · new Highway 400 freeway-to-freeway interchange, plus interchanges at Sideroad 10 and County Road 4 · Ontario projects the build supports more than 2,200 jobs a year and about $286M in GDP · the central and eastern sections through East Gwillimbury, toward Highway 404, are in detailed design
For East Gwillimbury specifically, the first shovels are at the Bradford end, not here. The stretch that ties into Highway 404, the part that touches EG most directly, is still in detailed design, so the visible work in town comes later in the schedule. Nobody's putting a firm opening date on the full route yet, and it isn't expected to open for several years. That's the same growth story the Town's Official Plan is built around, and part of why EG has been the fastest-growing town in Canada. If you're buying in EG today, you're early in that timeline rather than late, and what that's worth depends on your own plans.
Why It Matters for Buyers
Highway access is one of the things Buyers weigh most when they choose where to live. When a new freeway connection opens, travel times drop and the commuter catchment expands, so more GTA Buyers can consider the area. We've seen this pattern play out repeatedly: along the 407 extension, along the 412 and 418 in Durham, and along the 427 extension in Vaughan.
East Gwillimbury already has three Highway 404 interchanges. The Bradford Bypass adds a direct east-west link to Highway 400, turning EG into a genuine regional hub rather than a dead-end terminus. For commuters working in Barrie, Newmarket, Richmond Hill, or anywhere along the 400/404 corridor, East Gwillimbury becomes meaningfully more accessible. I break down the full commute picture, train and highway both, in my East Gwillimbury GO station guide.
Which Communities Benefit Most?
The northern communities are best positioned. Holland Landing, which sits closest to the planned interchange area, stands to benefit most directly from reduced travel times heading west toward Bradford and Highway 400. Queensville and Sharon benefit from the broader connectivity story. As EG's profile rises regionally, all communities within it see increased Buyer interest.
Properties along the Green Lane and Davis Drive corridors, which run east-west through the heart of EG toward the 404, are particularly well-positioned as the bypass improves east-west connectivity across the region.
The Timing Question
This is where it gets interesting for Buyers. Big infrastructure tends to get reflected in local prices in stages, if it gets reflected at all: first when a project is confirmed, then when construction starts, then when it opens. We are currently in the early construction stage. Where that leaves prices is never guaranteed, but understanding the stages is the point, so you can weigh it for yourself. The same logic is a big part of why buying pre-construction in EG's growth communities is worth understanding.
The bypass is not expected to open for several years, so anyone buying in EG today is doing so early in that timeline rather than late. What that means for any one home is for you to weigh.
Bottom line: The Bradford Bypass is a multi-year infrastructure project that will reshape east-west access across East Gwillimbury. If you're considering a purchase in East Gwillimbury, understanding this context is part of making a well-informed decision.
Common Questions
What is the Bradford Bypass?
It's a roughly 16.3 km freeway-standard highway that will connect Highway 400 in Bradford West Gwillimbury to Highway 404 in East Gwillimbury. The project, now designated Highway 425, is estimated at more than $1 billion and is in active construction, with the western section under way at the Bradford (Highway 400) end and the central and eastern sections through East Gwillimbury still in detailed design.
How will the Bradford Bypass affect East Gwillimbury property values?
Highway access is one of the things Buyers weigh most when they choose where to live. The Bradford Bypass adds a direct east-west link to Highway 400 on top of East Gwillimbury's three existing Highway 404 interchanges, which widens the commuter catchment. How that plays out in prices over time is not something anyone can promise, so it is worth weighing for your own situation.
Which East Gwillimbury communities benefit most from the Bradford Bypass?
Holland Landing sits closest to the planned interchange area and benefits most directly. Queensville and Sharon gain from the broader connectivity story, and properties along the Green Lane and Davis Drive corridors are well-positioned as east-west access improves.
Want to Talk Through What This Means for a Specific Property?
Location relative to the bypass route, proximity to interchanges, and community trajectory all vary. If you're looking at a specific property or neighbourhood in EG and want to understand how the bypass factors into its long-term value story, I'm happy to walk through it with you.
