    Station notice
    MARC Train has been notified by the Odenton MARC station parking garage construction team that the start of construction has been delayed. We anticipate that construction will begin later this week and will provide additional updates when they are received. When work begins, the first phase will result in closure of approximately 120 spaces in Lot B, in the part of the lot closest to the southbound platform. Signage has been posted on sandwich boards in the affected parking areas announcing the closure. Please do not park in any areas that are cordoned off or marked No Parking. Towing will be enforced for parking violations. There is ample parking available in the overflow lot on the north side of Route 175. To access this lot, cross Route 175 on Town Center Boulevard, turn right on Hale Street, then proceed straight into the MARC overflow lot. You may also put Hale Street & Lokus Road, Odenton, MD into your GPS device to get directions. Thank you for riding MARC Train.
