 Other road construction projects:

 N.M. 502 Roundabout and Road Reconstruction (NMDOT project)

See special notice above on lane shift to the south side. Otherwise, no change from last week’s report. East-bound N.M. 502 traffic detours onto 4th Street and Central Avenue. After a full stop, motorists turn right (east) and travel through the construction zone to continue east-bound out of Los Alamos on N.M. 502. West-bound N.M. 502 traffic entering Los Alamos and approaching the roundabout construction zone detours onto Central Avenue then west to Knecht Street then left to return to Trinity Drive. 

Project hours are 9 a.m. to 4:30 p.m. Monday through Friday. 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.

 TA-21 Clean Up Project – DP Road (N3B project):

No change from last week’s report. Clean-up work on the LANL TA-21 Site at the far eastern end of DP Road continues. Large trucks carrying away demolition debris containers will be exiting DP Road at an average of approximately three trucks per day. Motorists are asked to be alert for trucks exiting; use caution when entering or exiting DP Road, as this area is near the N.M. 502 Road Reconstruction project.

Oppenheimer Road Excavation

Marcon Excavating, Inc continues excavating a section of road located near 557 Oppenheimer with a traffic lane shift in this area. The project timeline has been extended and it is now anticipated to wrap up by Oct. 11. Motorists are urged to drive slowly through this work zone and watch for pedestrians.
