Facility Overview

The 300 Massachusetts Ave NW Garage is an expansive, modern subterranean parking facility serving the landmark Capitol Crossing development in downtown Washington, DC. Conveniently entered via 633 4th Street NW (between G Street NW and Massachusetts Avenue NW), this secure multi-level underground parking structure offers state-of-the-art parking infrastructure in the bustling East End and Mount Vernon Triangle commercial corridor. The facility features wide driving lanes, well-delineated parking stalls, bright LED illumination, and elevators that deliver direct, pedestrian-friendly access to the surface street level and building concourses.

In terms of vehicle suitability, the garage comfortably accommodates standard passenger cars, compact sedans, midsize crossovers, and full-size SUVs. However, as an underground commercial garage, a standard overhead clearance restriction applies (approximately 6 feet, 8 inches to 7 feet). Drivers of elevated pickup trucks with roof racks, commercial high-roof cargo vans, and vehicles with exterior attachments or bike mounts should carefully check the height warning bar at the 4th Street NW portal before descending into the garage.

Prime Location & Nearby Attractions

Positioned right at the intersection of Judiciary Square, Mount Vernon Triangle, and Penn Quarter/Chinatown, this garage offers an unbeatable base for visitors, government personnel, business travelers, and sports fans alike:

• Capital One Arena: Situated roughly a 7 to 9-minute walk (0.4 miles) away, making it a stellar parking spot to dodge congested arena traffic during Washington Capitals, Wizards, or concert events.

• Judiciary Square Courthouses: DC Superior Court, the E. Barrett Prettyman United States Courthouse, and surrounding administrative offices are reachable within a 5 to 7-minute walk.

Access, Navigation & Transit Connectivity

The entrance on 4th Street NW provides smooth, one-way vehicular ingress that minimizes conflicts with heavy Massachusetts Avenue traffic. Because Capitol Crossing was engineered directly over the Interstate 395 Center Leg Freeway corridor, access to and from regional thoroughfares is exceptionally swift. Drivers exiting the facility can quickly merge onto I-395 to reach Northern Virginia, the Southeast/Southwest Freeway (I-695), or Route 50 heading towards Maryland without navigating extensive gridlock.

For multi-modal transit users, the garage is surrounded by excellent public transportation options. The Judiciary Square Metro Station (Red Line) is merely 4 minutes away on foot, while the Gallery Place-Chinatown Station (Red, Green, and Yellow Lines) is a 7-minute walk. Metrobus stops along H Street NW and Massachusetts Avenue provide direct routes across the District, and Union Station is a straightforward 12 to 15-minute walk or brief rideshare away.

Visitor & Driver Tips

When planning your trip, keep in mind that weekday morning arrival hours (7:30 AM – 9:00 AM) and evening rush hours (4:30 PM – 6:30 PM) experience steady neighborhood traffic along 4th Street NW and Massachusetts Avenue. If you are attending an evening game or concert at Capital One Arena, booking a parking reservation via mobile platforms such as SpotHero or ParkMobile in advance guarantees your space and locks in a set tariff, shielding you from event-driven surge pricing. Always take a photo of your parking level and pillar number before heading up the elevators to ensure a seamless departure.
