Traffic Roundabout Construction
Sweeney-Nealy-Hammond Intersection
Langley is preparing for significant mission expansion of their flying and intelligence support missions. By 2025, recent traffic studies show the traffic density at the Sweeney-Nealy-Hammond intersection is expected to nearly double during the peak AM and PM commute. Construction of a traffic roundabout began June 13, 2022. This construction project will result in continuous traffic flow and prevent stop-go traffic along the Sweeney Avenue corridor as compared to the current traffic light control at the intersection.
