Duke Street is also seeing delays this week as the city installs new Smart Technology lights on Duke Street and Quaker Lane.
Delays and brief signal flashes at:
Duke Street & N. Quaker Lane – April 21
Duke Street & S. Quaker Lane – April 23
"While our crews work to improve these intersections, residents and commuters should plan extra travel time or use alternate routes if possible. We appreciate the community’s patience as we work to improve traffic with new technology."
Here's the city website on this upgrade, although the dates of service came to our attention from TES project emails. https://www.alexandriava.gov/transportation-planning/adaptive-signal-control
King Street - Commonwealth intersection also was seeing delays Monday morning as Virginia Railway Express prepares for bridge reconstruction.
Smart signals respond in real time to traffic, reducing congestion and adapting to changing conditions.
