Work hours are 6 a.m. to 6 p.m., seven days a week. This paving work will be completed in two phases. Phase 1 (yellow) beginning on Sept. 7, and Phase 2 (green) in mid-September.
Los Alamos Police Cmdr. Christopher Ross advises motorists, “With increased congestion and delays expected during this project, we remind everyone to stay patient and drive safely. Allow extra time for your commute, stay alert, avoid distractions, and obey posted speed limits as well as traffic control signs and flaggers. Your attention to safety helps keep drivers and road crews safe.”
Fencing to be installed around Los Alamos National Laboratory’s Health Research Laboratory
Los Alamos National Laboratory’s Health Research Laboratory (HRL) complex, adjacent to Los Alamos Medical Center on Diamond Drive, is being emptied for pre-demolition preparation activities. Fencing around the perimeter of the complex is expected to be installed in the next couple of months. Most of the parking used by hospital staff and patients between the medical center and HRL will remain open and may continue to be used. Parking will be reassessed for safety prior to construction mobilization. A gate will be installed under the Los Alamos Canyon (Omega) Bridge to prevent unauthorized access.
The facility characterization process will start in 2026 with physical demolition beginning in the next five to seven years.
HRL previously housed the Bioscience division. All Bioscience work has been moved elsewhere on the LANL campus and to leased commercial buildings.
