NIH Security
All visitors must access NIH via the NIH Gateway Center, adjacent to the Medical Center Metro station at the South Drive entrance to the NIH campus from Rockville Pike/Wisconsin Avenue (Route 355). It combines visitor parking, noncommercial vehicle inspection and visitor ID processing, all in one location. NIH will process all visitors in vehicles or as pedestrians.

NIH guests will be required to show one form of identification (a government-issued photo ID — driver’s license, passport, green card, etc.) and to state the purpose of their visit. In preparation for access to NIH’s campus, all meeting attendees (even those who have been to NIH before) are encouraged to review the detailed campus access and security requirements.

Please allow approximately 30-45 minutes for passing through NIH security. The NIH Visitor Map has additional information about specific security requirements (including vehicle inspection) and information regarding the visitor entrance.

NIH Visitor Information
NIH visitors can find detailed information on NIH’s Visitor Information page, including directions, maps and public transportation.

The William H. Natcher Building (Building 45) is a short walk from the Medical Center Metro stop on the NIH campus. Attendees are encouraged to use the Metro because parking is limited on NIH’s campus. Visit the Washington Metropolitan Area Transit Authority website for schedules, maps, a trip planning tool, and additional public transportation information.

Visitor parking is extremely difficult to find at NIH, so alternative transportation methods are recommended.

Short-term metered parking and long-term attendant-controlled parking are available to visitors at a cost of $2 per hour for the first three hours or $12 per day.

The Gateway visitor complex includes MLP-11, a 342-space multilevel underground parking garage. This visitor-only lot is the primary visitor parking for the NIH main campus. We strongly encourage all visitors to park in this garage. Vehicles parking in MLP-11 are outside of the perimeter security and will not go through vehicle inspection, reducing the amount of time it takes to get on campus. Visitors parking in MLP-11 should proceed to the Gateway Center to get a visitor badge and either walk or take a shuttle bus to their destination.

NIH Shuttle Buses
Once on the NIH campus, visitors can take the free NIH campus shuttle bus to get to the William H. Natcher Building (Building 45), which is within walking distance from the NIH Gateway Center.
