Drivers passing through north Frisco will have to tap the brakes for about three years.

Frisco City Council on Jan. 18 approved a temporary speed limit reduction along US 380. The speed limit was lowered from 60 mph to 50 mph from the city’s western limits to the line between Denton and Collin counties.

The Texas Department of Transportation this year is working to widen the highway, according to city documents.

The highway is being expanded from four to six lanes of traffic from the town of Crossroads to the Denton County and Collin County line, the documents stated. In addition, grade separations will be placed at FM 423, Championship Drive and Legacy Drive.

TxDOT has requested all cities within the project limits reduce the speed limit on US 380 to 50 mph, according to the city.


At the end of construction, TxDOT will perform speed studies and make recommendations for a new permanent speed limit, city documents stated. The project is expected to last three years.

Those who exceed the speed limit could face a misdemeanor charge and a maximum fine of $500, according to the city’s updated ordinance.
