Visitor's Guides (Including Maps):
The NLM may be reached by road (see map) or via the Washington, DC Metro underground railway system. You are encouraged to use Metro whenever possible; due to several concurrent building projects underway at NIH, parking (particularly for visitors) is in extreme shortage, and parking regulations are strictly enforced with tickets and tow trucks. If you must drive, consider using the supplementary off-site parking lots, which are served regularly by shuttle buses.
The NLM/NIH is accessible from any of the three major regional airports (see instructions for Dulles International Airport, Baltimore Washington International Airport, and Washington National Airport).
