What’s Happening?

Construction for the new NIEHS Main Entrance is planned to begin June 1, 2018. A new guard house and inspection canopy will be constructed to improve the security and safety of employees and provide an updated, sheltered, and more secure NIEHS Campus entrance. Work will continue until early February 2019.

Visitors traveling via Alexander Drive should enter our campus through the EPA entrance. Directional signs will be posted.

After passing through the campus entrance security, follow the road to the roundabout and take the second exit. Follow the signs to "Clinical Research Unit.” The CRU will be located on the right side; patient parking is across from the building entrance.
