Oversized Crane Transport on NM502 Through Downtown to Los Alamos Ice Rink – Morning of Wednesday, July 2

As part of the project to install a new chiller at the Los Alamos Ice Rink, a 140-ton crane and one tractor-trailer will be traveling through Downtown Los Alamos on route to the Ice Rink on West Road on Wednesday July 2 between 9:00 am and noon.

Due to its weight the crane and the tractor-trailer cannot cross the Omega Bridge and therefore will be traveling up the Main Hill on NM502/East Rd, then through Trinity Dr. to Diamond Dr. before turning onto West Rd. to the Ice Rink.  If needed, the Los Alamos Police Department will provide escorts to the crane on its way up NM502 and travel through downtown.

Crane operations at the Ice Rink are scheduled for July 2 and will be contained within the Ice Rink parcel.  A temporary closure of West Rd. may be needed to allow the crane and the tractor-trailer to maneuver into the Ice Rink parking lot and the space behind the Ice Rink garage.  The closure will be removed after the crane and tractor-trailer have safely cleared West Rd.  The Public Works Department has designed a temporary traffic control plan to assist the travel of the crane and temporary closure of West Rd.

Access to the Ice Rink Trailhead may not be possible as the front and west parking lots will be closed July 1 and 2.

Traffic control devices along West Road will be set up on July 1.  The Los Alamos Ice Rink front parking lot will be closed from Noon on Tuesday July 1 until the afternoon of Wednesday July 2, 2025.

The crane’s departure is scheduled to occur on Wednesday July 2 and will follow the route used for its arrival. The cranes departure will occur outside peak traffic hours.  If needed, the Los Alamos Police Department will provide escorts to the crane on its way along NM502 out of town. 

Residents and visitors are urged to use caution to safely travel up NM502 and through town.  Travelers between TA-43 and TA-62 are urged to use caution to safely navigate through West Road.

Los Alamos County appreciates your patience and diligence as this important component to the Los Alamos Ice Rink is put into place.

For any questions, please call the Public Works Department at 505-662-8150.

Performing Arts Center Parking Lot Closure

Access to the parking lot at the Performing Arts Center (PAC) building (a.k.a. "Little Theatre") at 1670 Nectar Street in Los Alamos, is closed to the public.

The closure will allow a much-needed health and safety focused renovation project to begin, aimed at improving the fire safety response time in case of emergencies. The project also includes abatement of asbestos materials from the ceilings and flooring of the PAC. The County secured the services of R & M Construction, LLC, to perform the installation of a Fire Suppression System, and Southwest Hazard Control, Inc. to perform asbestos abatement services.

The project is scheduled for completion by the end of October 2025. For more information, contact Sayeda at sobia.sayeda@lacnm.us or 505.661.2051.

LAFD Hydrant Testing Begins

The Los Alamos Fire Department (LAFD) will be testing fire hydrants throughout the county through September 1. The purpose of testing is to ensure that the hydrants will provide an adequate water supply for fire suppression and to flush out sediments that have accumulated in the water distribution system over the past year. These tests are part of the regular hydrant maintenance program and are conducted jointly with the Los Alamos Department of Public Utilities (DPU). Residents will see LAFD firefighters and vehicles throughout the community releasing water through the hydrants while they are conducting these tests.

Residents may see some discoloration in their water due to the amount and volume of flowing water after nearby hydrants are tested. If this is the case, residents should run the cold-water spigot located outside their home for a few minutes. This will usually resolve the issue. It is also recommended that residents avoid washing laundry until the water runs clear. 

Questions or concerns about this annual maintenance can be directed to the, Los Alamos County Customer Care Center at 505-662-8333 or CustomerCare@lacnm.us.
