Analyst Commentary
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.
Buy now in north McKinney, but pick carefully. Trinity Falls, Erwin Farms, and Tucker Hill will benefit most once the bypass opens. Avoid properties directly on current US 380—the noise and congestion aren't going away for 7+ years. This is a long-term play: buy for 2030+, not 2026. The fundamentals are strong, but patience is required.
