Westbound N.M. 502 (Main Hill Road) leading to Los Alamos will be closed to all traffic Saturday, Aug. 25 (see map in purple). The hairpin ramp connecting N.M. 4 to westbound N.M. 502 will also be closed (see map in blue).
These traffic control measures are to allow completion of mill and inlay work on an approximately one mile stretch of N.M. 502. Signage will be posted to detour traffic around the closures via East Jemez Road (truck route).
As previously announced, westbound N.M. 502 traffic (see map in red) will be narrowed to one lane beginning today, Aug. 23. Lane closures are anticipated to extend into Monday evening, Aug. 27, unless favorable conditions allow work to be completed Sunday.
If construction activities continue into Monday, drivers should anticipate back-ups during the morning hours due to heavy traffic volume on the single lane and plan their travel accordingly. Law enforcement will be present to ensure compliance with traffic control measures.
Eastbound N.M. 502 full-depth reconstruction should be completed today, Aug. 23, opening both lanes for the evening commute.
Crews will continue mill and inlay operations on various parts of NM 502 during the coming days. Updated information on the planned sequence of those operations will be posted on Tuesday, Aug. 28. Crews will also apply a second coat of stripping paint on East Jemez Road and other affected parts of N.M. 4. Please be aware of the shadow car following road-striping crews.
The road improvements to East Jemez, N.M. 4 and N.M. 502 should be completed by the end of September.
