Facility Overview

The NIH Gateway Visitor Parking facility (Multi-Level Parking 11 / MLP-11) is the official public and visitor parking structure for the National Institutes of Health (NIH) main campus in Bethesda, Maryland. Situated along NIH Gateway Drive immediately off Rockville Pike (MD-355), this facility serves as the primary gateway for all non-badged visitors, scientific collaborators, clinical trial participants, patient family members, and official campus guests. The parking complex features a modern multi-level covered garage structure integrated with the NIH Gateway Center (Building 66) security screening complex. The facility provides standard passenger stalls, dedicated handicap-accessible spaces, and well-marked traffic corridors. Due to covered ceiling clearances of approximately 7 feet (2.13 meters), standard passenger sedans, crossovers, and mid-size SUVs can park effortlessly, while oversized utility vehicles, lifted pickup trucks, and high-roof vans are routed through dedicated ground-level inspection checkpoints and adjacent surface staging areas.

Prime Location & Nearby Attractions

Positioned on the eastern boundary of the world-renowned 300-acre biomedical research campus, this facility offers unparalleled proximity to crucial healthcare and research institutions. Prominent destinations within walking distance or a short campus shuttle ride include:

• NIH Clinical Center (Building 10): The largest clinical research hospital in the United States, located roughly an 8- to 10-minute walk or a quick ride on the NIH internal shuttle.
• National Library of Medicine (NLM / Building 38A): The world’s largest biomedical library and home to PubMed, situated less than a 5-minute walk from the Gateway Center.
• Walter Reed National Military Medical Center: Located directly across Rockville Pike (MD-355), accessible via the Medical Center Metro underpass within a 5-minute walk.
• Uniformed Services University of the Health Sciences: Situated immediately across the eastern campus boundary adjacent to Walter Reed.
• Downtown Bethesda: Located just 1.5 miles south, featuring hundreds of dining spots, boutiques, art galleries, and cultural venues like the Bethesda Theater and Bethesda Row.

Access, Navigation & Transit Connectivity

Accessing the garage requires approaching from Rockville Pike (MD-355) and turning onto South Drive/NIH Gateway Drive. Because NIH is a secure federal installation, all visitor vehicles must enter through the Gateway Vehicle Inspection Station where drivers and passengers undergo security screening and credential verification before entering the parking decks. Exiting back onto Rockville Pike is straightforward, though drivers should anticipate heavier volumes during peak government commuting windows (7:30 AM–9:30 AM and 4:00 PM–6:00 PM). The location offers exceptional transit connectivity, sitting directly adjacent to the Medical Center Metrorail Station (Washington Metro Red Line) and multiple Montgomery County Ride On and WMATA Metrobus routes. Major arterial routes including Interstate 495 (Capital Beltway) and Interstate 270 are reachable within minutes via Rockville Pike.
