The 16.2 mile long Purple Line is under construction across the alignment from Bethesda to New Carrollton. Currently most of the work happening is heavily related to utility relocation both overhead and underground to make way for the Purple Line. Additional work taking place includes excavation and building retaining walls, creating the Plymouth Street Tunnel, building the operation and maintenance facilities, and work on bridges such as Lyttonsville Place Bridge and Rock Creek Bridge. The construction phase of the project is projected to last through 2027.

Construction of the Purple Line will be impactful as are all major construction projects. Stay up to date with construction activities by subscribing for construction updates.

During construction:

  • Pedestrian detours are clearly marked. If a full closure is required a detour route will be provided while flaggers may be utilized for partial closures.
  • Access will always be maintained to businesses and residences
  • Where applicable variable message signs (VMS) will be used to provide additional information to the public
  • Notifications to the public are provided before closures occur through PLTP’s construction alerts.
Safety: Stay out of the work zone-there are many unforeseen hazards for pedestrians; Avoid the marked construction zones-plan your driving route around work zones; Follow all construction and detour signage; Exercise caution when driving and walking near work zones; Take control of your safety-don’t be distracted while driving or walking; Your phone can wait, safety can’t.
