On Monday, October 6, 2025, the U.S. 380 project moves from planning to pavement. Night work starts west of Princeton near Airport Road in McKinney and will move east in segments:
Airport → New Hope → Bridgefarmer → through Princeton → Boorman Lane.
Crews will work six nights a week, with Sundays off. Daytime lanes stay open, but traffic will be squeezed through lane shifts and construction barrels. The project is expected to take about two and a half years.
More Than Just Repaving
This is part of TxDOT’s larger plan: a new controlled-access freeway north of Princeton and a widening of the existing 380 corridor, including the stretch across Lavon Lake to CR 560.
Princeton’s segment will expand to six lanes, with frontage roads added over time.
Near-Term Impacts
Residents can expect:
- bright construction lights at night
- heavy equipment noise
- narrowed lanes
- increased cut-through traffic in neighborhoods
Contractors must coordinate before closing side streets, though enforcement often becomes inconsistent once the work begins.
Why Now?
Traffic has long exceeded what the road was designed to handle.
TxDOT’s 2020 Feasibility Study showed Princeton carrying 49,000 vehicles per day in 2017, already near freeway capacity.
By 2045, projections reach 86,000 vehicles per day, with peak volumes potentially exceeding 100,000 daily trips.

Property Impacts
TxDOT’s Finding of No Significant Impact shows a 320- to 536-foot right-of-way corridor.
That expansion displaces:
- 18 homes
- 17 businesses
- 1 non-commercial property
In McKinney, Jason’s Deli, White Rhino Coffee, and 3Natives have already closed citing the project.
One Princeton family has publicly stated they are losing their home to eminent domain.
Why It Matters
Princeton, now the fastest-growing city in America, adopted a housing moratorium through November 30, 2025 because infrastructure could not keep pace with development.
The US-380 project is part of the same underlying issue: population growth moving faster than roads, utilities, and transportation planning.
What Happens Next
Night construction begins October 6 near Airport Road and will gradually move east toward Boorman Lane.
Expect closures six nights per week for roughly 2.5 years, depending on weather, utilities, and construction progress.
How Residents Can Help
- Send photos of closures or backups.
- Share commute times before and after construction.
- Report unsafe neighborhood cut-through routes.
Bottom Line
TxDOT promises congestion relief in two and a half years.
The Princeton Journal will track every closure, every delay, every cost, and every displacement as the project moves forward.
