Public Works/Traffic Division projects:

Central Avenue Closure for Independence Day events:

Pedestrians and motorists are to be advised that Central Avenue from Oppenheimer to 15th will be closed the morning of July 4 for the Y adult 5K run and then the children’s firecracker parade.

Manhole Repairs – Ponderosa Estates in Los Alamos: 

Beginning Monday, crews will be adjusting manholes in the Ponderosa Estates area. Work will begin on Aspen Drive at Range Road and continue along Aspen Drive, Sumac Lane and Maple Drive before finishing back at Aspen Drive. Since there dozens of manhole adjustments in this subdivision, construction is scheduled to continue through July 31. The concrete being used is a high strength mix and will require a cure time; therefore, residents are urged to avoid driving over these manholes for the first few days after they are poured. Traffic control will be set up daily in several locations along the project route and residents are urged to use caution when driving through and walking near these work zones. Work hours are 8:00 a.m. to 5:00 p.m. Monday – Friday.

Road Striping in White Rock:

Traffic and Streets Division crews continue striping local roadways to replace faded markings for traffic safety. Crews have finished in Los Alamos and moved on to White Rock. Work will continue until main roadways are finished; all work is expected to wrap up mid-July. Work is weather dependent. No traffic delays anticipated that will impede traffic flow; please slow down and use caution when crews are working in these areas.

Other road construction projects:

NM502 Roundabout and Road Reconstruction (NMDOT project) 

No change to traffic pattern for last week. No work on July 4 or 5 because of the holiday. The contractor continues working on common trench for utilities from 9:00 am to 4:30 pm. Monday – Friday. Expect delays. The speed limit is reduced to 25 mph. NM502 (Trinity Drive) east-bound traffic is being detoured to 4th Street and Central Avenue. After a full stop, motorists should turn right (east) and travel through the construction zone to continue east-bound out of Los Alamos on NM502. West-bound NM502 traffic entering Los Alamos and approaching the roundabout construction zone is being detoured onto Central Avenue; continue west to Knecht Street (or alternatively, continue to the traffic light at 15th Street) then turn left to return to Trinity Drive. There is only one lane of traffic in each direction on Central Avenue. Please slow down, use caution and expect delays in this area, especially during peak commute times.

Traffic advisories from NMDOT are available on and motorists are asked to check the site for updates on this project as it proceeds.
