Reminder: North Drive Only Open for Outbound Traffic on Weekday Afternoons​/Evenings

As a reminder, North Drive is now open for exiting on weekdays from 3pm – 7pm. It is NOT open for exiting at any other time. The inbound traffic hours of operation remain weekdays from 6am – 10am. The NIH Police are witnessing some staff vehicles attempting to exit during these morning hours causing a safety issue. 

The opening of North Drive to exiting traffic is part of the NIH Building for All campaign (, a joint effort of the Office of Research Services and the Office of Research Facilities to address traffic and parking issues associated with major construction projects on the northwest portion of the Bethesda campus. 

Additional information about other upcoming changes, suggestions on where to park and enter campus based on where you live and work, and the most up-to-date information to the NIH campus related to parking, traffic and associated construction are available at the NIH Traffic website: For traffic/parking/access questions, use the ORS Information Line at or 301-594-6677.
