​Wilson Drive/Rockville Pike Reduced Access from June 4 to July 20 for Construction

The NIH will replace vehicle barriers at the Wilson Drive entrance off of Rockville Pike (MD355) beginning Monday, June 4, 2018. This work will require the entrance to have restricted access from Monday, June 4 through Friday, July 20.

The construction will be conducted in two major phases. In general, during both phases, Wilson Drive will be used for inbound traffic during the morning and early afternoon, and outbound traffic during the afternoon and evening. During both phases, the sidewalk and pedestrian gate will remain open for normal pedestrian access.

Phase 1: 6/4/2018 – 7/1/2018.

6:00am – 2:00pm: Inbound lanes used for inbound traffic only. (No outbound traffic).

NIH Bethesda Campus Winter Safety Advisory

The winter season is almost here, and that means snow can't be far behind.

The Office of Research Facilities (ORF) Division of Facilities Operations and Maintenance is prepared to ensure safe access so that 'Snow Does Not Stop Science.' Their mission is for a safe and timely snow removal. The contractor operates heavy equipment to quickly remove snow from the Bethesda campus. While walking or driving near heavy equipment, please exercise caution and do not assume the operator can see or hear you.

On the same topic of safety, while most of the sidewalks will be free of snow and ice, melting and refreezing will most likely occur. Please exercise caution and consider wearing non-skid shoes. 

Starting the last weeks of November, you will begin to notice orange, yellow, red and blue markers throughout the Betheda campus. The NIH snow removal contractor uses these markers to minimize damage to the grass and other campus plants, help the crews avoid hydrants, and prevent collisions with other structures that could be covered by deep snow. Please help support our mission of safe and timely snow removal by keeping the markers in place. If the markers are removed, it increases the likelihood of mishaps that could injure an employee or snow removal crew member and cause property damage.

View the snow removal informational flyer complete with live traffic camera links and a snow removal priority map. Employees can determine which routes are safe inside and outside of campus. If you need special assistance during a snow event, please call the ORF Help Desk at (301) 435-8000.

Medical Center Metro Escalator Replacement

The Washington Metropolitan Area Transit Authority (WMATA) is beginning a major capital improvement project to replace the three escalators at the Medical Center Metrorail station. The current escalators have exceeded their useful life and will be replaced with new, reliable and durable escalators.  Metro's contractor, KONE, will install the new escalators as part of Metro's ongoing project to replace 128 escalators across the Metrorail system. The project is expected to take about 2.5 years, as most of the work will be conducted while the station is closed. During construction, one escalator at a time will be replaced, leaving access to the remaining two escalators. For more information and the full article, click here.
