Updated: Sept. 5 @ 3 p.m.

Several separate construction projects will impact roads, gates, and parking at the Lab’s hill site in September. The Projects & Infrastructure Modernization Division is committed to providing the Lab community with timely and comprehensive information on construction disruptions.

The map below provides a snapshot of the closures, and complete details are listed below the map.  Please review the details and plan your hill site visits accordingly.

PIM's primary goal is to ensure the safety of everyone working at the Lab. Thank you for your patience as we improve the Lab for the future.
