Construction Updates: New Carrollton Metrorail Station Projects

Advisory Effective: 7/1/19 - 12/31/26

Metro and its developer are transforming the New Carrollton Metrorail Station into a first-class, multi-modal and mixed-use development, with entertainment, residential, retail and commercial office space. The plan includes an urbanized town center and walkable community, connected by one of the region’s largest transit hubs with access to Metro, Amtrak, MARC, Greyhound and the future MDOT MTA Purple Line.  

During construction, temporary pedestrian and traffic detours may be in place. For your safety, please follow all construction notices and signs.
