Campus Drive Detour Set for Purple Line Work

Campus Drive in the DC-Maryland-Virginia area faces a temporary detour as Purple Line construction continues, transit officials said. WMATA implemented the route change January 17, affecting commuters and residents who regularly use the corridor. Officials didn't specify how long the detour will remain in place or which specific streets will serve as alternate routes.
The Purple Line represents a major expansion of the region's transit infrastructure, connecting communities across Maryland with a 16-mile light rail line. Construction on the long-planned project has required periodic road closures and detours as crews build stations, lay track, and install overhead power systems. Transit agencies typically coordinate with local jurisdictions to minimize disruption during major construction projects, though specific coordination details for this detour weren't available. The work on Campus Drive appears to be part of the broader construction timeline for the Purple Line system.
