Facility Overview

The Atlantic Parking facility at 12721 Twinbrook Parkway is a comprehensive, multi-level covered parking garage serving the Fishers Place and Twinbrook commercial corridor in Rockville, Maryland. Constructed as a seven-story, 295,000-square-foot structured deck, this facility provides substantial off-street capacity designed for daily visitors, business professionals, and monthly parkers alike. The garage features an intuitive, dual-entry design with dedicated lanes that separate daily transient visitors from monthly access-card holders, ensuring smooth traffic flow during peak morning and evening rushes. The facility enforces a maximum vehicle clearance height of 6 feet 8 inches (2.03 meters), comfortably accommodating standard sedans, compact cars, station wagons, crossovers, and stock full-size SUVs and pickup trucks. However, high-roof conversion vans, oversized commercial utility trucks, and passenger vehicles with elevated roof racks or rooftop carriers exceeding the 6'8" threshold will not clear the overhead portals and should arrange surface alternatives.

Access, Navigation & Transit Connectivity

Vehicular ingress and egress are exceptionally straightforward along the eastern perimeter of Twinbrook Parkway, situated between Fishers Lane and Ardennes Avenue. The garage operates two clearly marked portals: the northern entrance is dedicated specifically to registered monthly contract parkers, while the southern entrance—marked by an automated ticket kiosk and cashier booth—is designated for transient daily visitors. Twinbrook Parkway serves as a crucial arterial connector, allowing drivers rapid access to MD Route 355 (Rockville Pike) to the west and MD Route 586 (Veirs Mill Road) to the east. Regional highway connectivity is equally efficient, with Montrose Parkway and the Montrose Intertie providing express access to Interstate 270 (I-270) and the Capital Beltway (Interstate 495).

For multi-modal transit travelers, the location offers seamless transfers. In addition to the nearby Twinbrook Metro Station, several Montgomery County Ride On bus routes (including lines 5, 26, and 46) stop directly along Twinbrook Parkway and Fishers Lane, allowing visitors to easily switch between driving and Montgomery County transit networks.

Visitor & Driver Tips

When approaching the garage along Twinbrook Parkway, pay close attention to the entrance signage: keep right and proceed to the southern barrier gate if you are a daily visitor, as the northern gate is strictly card-access for monthly parkers. If you pre-book your space using apps such as SpotHero or ParkChirp, pull a standard entry ticket at the gate as normal, and follow the mobile app checkout instructions (or use the intercom call button to provide your reservation ID) when exiting. Keep in mind that standard daily parking reservations do not support in-and-out privileges once you leave the structure. If you are visiting nearby federal facilities at 5600 or 5601 Fishers Lane, allow an extra 10 to 15 minutes before your scheduled appointment to clear physical security checkpoints and identity badge verification at the agency lobby desks.
