​​Temporary Access Change: Lincoln Drive Reopens; South Drive Closes for Week of May 9-13

Due to the need to again assemble a crane on South Drive near Buildings 37 and 40, the Lincoln Drive/Old Georgetown Road entrance/exit will reopen for normal hours of operation (6am – 7pm, Monday - Friday) during the week of May 9 - 13. During this same period, South Drive from Old Georgetown to Convent Drive will be closed. This will allow the NIH to maintain two open entrances/exits on weekdays during this period of significant construction on the western side of the Bethesda campus. The crane work on South Drive is part of the construction of the new MLP-14 patient parking garage and utility vault. 

On May 16, these two entrances/exits will revert back with South Drive/Old Georgetown Road reopening on weekdays, 6am – 7pm, and Lincoln/Old Georgetown Road closing through August 2022 for widening, intersection and safety improvements.

For a complete list of the ‘regular’ hours of operation for other entrances/exits, please visit the NIH Employee Access Map.        

The NIH recognizes and appreciates the considerable adjustments staff are making as we undertake these major, critical improvements to our research capabilities, patient experience and hospital operations. Additional information about upcoming changes, including suggestions on where to park and enter campus based on where you live and work and the most up-to-date information related to parking, traffic and associated construction are available at the NIH Traffic website.
