8-lane freeway bypass around north McKinney, Blue Alternative selected, part of $8B corridor plan
Sofee’s read
Buy now in north McKinney, but pick carefully. Trinity Falls, Erwin Farms, and Tucker Hill will benefit most once the bypass opens.
$2.8B
2026–2032
Land acquisition underway, construction 2026+
What could happen
If it goes well
The bypass opens on schedule (2032) and transforms McKinney's connectivity. Commute times to Dallas drop 15-20 minutes. The current 380 corridor becomes a local road, enabling walkable redevelopment. Home values in north McKinney (Trinity Falls, Erwin Farms) surge 20-30%. McKinney finally escapes its 'traffic nightmare' reputation.
Watch out for
TxDOT projects routinely run 2-4 years late and 30% over budget. If the bypass slips to 2035, McKinney endures a decade of construction chaos. The current 380 remains gridlocked. Buyers avoid McKinney entirely, choosing Celina or Prosper instead. Property values stagnate while Frisco and Allen continue appreciating.
What this means if you buy nearby
The Big One: $2.8B for an 8-lane freeway bypass around north McKinney. This is the largest infrastructure project in Collin County history. If you live along the current US 380 corridor, your daily commute is about to transform—eventually.
Timeline Reality: Construction starts 2026, completion 2032. That's 6+ years of disruption. Current US 380 will remain congested during construction, possibly worse due to lane closures and detours.
Property Value Split: Homes on the current 380 corridor may depreciate as traffic noise and commercial blight persist. Homes near the new bypass alignment could appreciate once it opens, but will endure construction impacts first.
