As of November 2025, major progress is being made on the U.S. 380 expansion through Denton County, especially around FM 423 and the Legacy Drive corridor, right in the heart of the areas many Somerset Park residents drive through daily.

Project Status and Traffic Changes

Overpass Openings:

The Legacy Drive overpass officially opened ahead of schedule in October 2025, offering a smoother drive across U.S. 380. Other key overpasses like Teel Parkway, Navo Road, and FM 720 are close behind and expected to open soon. Once complete, these new grade-separated intersections will eliminate several traffic lights and help reduce congestion that’s long plagued the corridor.

Bridge Construction:

Crews have finished paving bridge decks at several intersections, including FM 423/Gee Road, following earlier lane closures in 2025. The final beam for the Navo overpass was set in September 2025, marking another milestone for the project.

Corridor Improvements:

U.S. 380 is being widened to three lanes in each direction, with new frontage roads, turn lanes, sidewalks, and modernized traffic signals all part of the upgrade. The project aims to improve both daily traffic flow and long-term safety for drivers and pedestrians.

Traffic Impacts and Upcoming Closures

Lane Shifts and Detours:

Drivers should continue to expect lane shifts, narrowed frontage roads, and temporary detours while construction crews finalize service roads and on/off ramps.

New Traffic Patterns:

With the new overpasses opening, traffic patterns are changing. Through-traffic on U.S. 380 will now flow over intersections, while local access will shift to the frontage roads below. Be sure to watch for updated signage and follow posted speed limits in construction zones.

Expected Completion Timeline

TxDOT anticipates that the entire U.S. 380 corridor through Denton County from Loop 288 to the Collin County line will be completed by spring 2026. Officials say drivers can expect a “completely transformed” roadway by March 2026.

Local Tip: Morning and evening commuters from Somerset Park should allow a few extra minutes when heading east or west on U.S. 380, especially near FM 423 and Legacy Drive as crews finish up final paving and ramp work through early 2026.
