There are two parking lots we recommend:
Parking Garage A is the closest option (Directions). There is a small fee, but you get 2 hours free if you validate your parking ticket (at a scanning machine set up on the first floor of the library).
Free Parking – by the M&T Bank Sign (free after 6PM)
4 E Montgomery Ave, Rockville, MD 20850

This lot is free after 6PM.
The library is only an 8 minute walk from the Rockville Metro Station.
