Project Goals and Scope

The US 380 Improvement Project is designed to reduce congestion, enhance road safety, and support future growth. The main improvements include:

✅ Widening US 380 – Expanding the highway from four to six lanes with a curbed median for better traffic flow.

✅ Constructing grade separations (overpasses) – Separating local and highway traffic to reduce delays at major intersections.

✅ Adding continuous frontage roads – Creating two and three-lane frontage roads to improve business and residential access.

✅ Improving pedestrian access – Enhancing sidewalks and crossings to make the highway safer for pedestrians and cyclists.

These improvements will make it easier to travel across North Texas and support the rapid development of businesses and neighborhoods along the corridor.

Construction Locations and Boundaries

The US 380 construction affects several North Texas communities, with each area undergoing specific improvements:

Little Elm (FM 720/Oak Grove Parkway to Doe Creek)

🔹 Expanding the highway from four to six lanes.

🔹 Building grade separations to improve traffic flow at key intersections.

🔹 Adding safer pedestrian access near businesses and schools.

Prosper (FM 1385 to Legacy Drive)

🔹 Installing new overpasses to prevent bottlenecks.

🔹 Constructing continuous frontage roads for better local access.

🔹 Implementing road safety enhancements for both vehicles and pedestrians.

Frisco & McKinney (Championship Drive to Lake View Drive, east of Coit Road)

🔹 Expanding US 380 to six lanes.

🔹 Upgrading intersections to improve traffic flow.

🔹 Preparing for future expansions to accommodate population growth.

Each of these projects is crucial in making US 380 a safer and more efficient roadway for North Texans.

Traffic Impacts & Road Closures

Expect major traffic delays along US 380 due to lane closures, detours, and construction zones. TxDOT is working to minimize disruptions, but drivers should plan for extra travel time and use alternative routes when possible.

🚧 Legacy Drive Overpass – Bridge beam installation has started, leading to periodic lane closures and detours.

🚧 Teel Parkway Intersection – Lane closures continue for overpass construction.

🚧 FM 1385 Intersection – Recently reopened ahead of schedule, helping improve traffic flow.

🚧 Windsong Parkway Closure – Closed for reconstruction of the approach to US 380, causing detours.

Drivers should stay updated on road closures and follow posted detour signs for alternate routes.

Project Timeline & Completion Dates

The US 380 Improvement Project is expected to continue until Spring 2026, though timelines are subject to change. Key milestones include:

📆 2024 – Major overpass construction and highway expansion begin.

📆 2025 – Most widening efforts and grade separations completed.
