A new visitor parking lot (Lot 18) is now available for NIH visitors and replaces visitor parking Lot 4A, now being used for patient valet parking. The new paid-parking lot offers 104 spaces and is located adjacent to Lot 42 and across from Building 41. Parking is available Monday-Friday, from 6:00 am to 9:00 pm. The hourly rate is $2.00 for the first hour, $4.00 for the first two (2) hours, and $6.00 for the first three (3) hours. Beyond three hours is considered “all day," which costs $12.00. Lot 18 will be serviced by the NIH Campus and Campus Limited shuttle routes. A shuttle stop has been added to this location for the convenience of visitors.
