DP Road Phase II Reconstruction Project Ramps-up
Los Alamos County Public Works Department, with contractor TLC Plumbing & Utility, is on its initial ramp-up for the project, and businesses and visitors will be progressively seeing construction activity. Parking restrictions began May 6 along the south side of DP Road. TLC is performing potholing of existing utilities in this area along the south side of DP Road and is also in the process of creating new parking just south of the ACE Hardware Store. Once the parking area is complete, it will be available for public parking. This is anticipated within the next week.
Los Alamos County has opened up an additional temporary parking area within the Los Alamos County parcel directly across and south of the Los Alamos Fire Training Academy. This area is also available to the public.
Work zone traffic control will be commencing soon. This will include a lane shift eastbound on DP Road from the Fire Academy property along the work zone to CrossFit Los Alamos Gym. Once traffic control is placed, please follow all work zone signs and exercise caution around the work zone. Flaggers may also be present to direct traffic during certain construction events, both east and westbound. Access to businesses will be maintained and westbound traffic from the TA-21 gate to the beginning of the project will be in its current alignment at this time.
Services such as mail delivery, trash and recycling collection, and emergency services will be maintained. Businesses can expect large equipment and construction noise.

Quemazon Place Road Repair Scheduled
Three gate valves in the Quemazon subdivision sprung leaks recently. The rushing water of the first two and subsequent repairs destroyed a section of roadway. Los Alamos County Department of Public Utilities (DPU) and the Los Alamos County Traffic and Streets Division collaborated on a plan to fix the road that began May 6.
The work zone, which is on Quemazon between Tranquilo and Corona, is now open, and much of the roadway has been replaced. However, three smaller patches still need attention. Drivers are asked to exercise caution near the cones and barricades surrounding the remaining patches. Public Works crews will address these patches as soon as possible during dry weather.
The water breaks were due to corrosion on the underground piping system. DPU staff has developed a plan to proactively replace valve hardware in the subdivision as the pressure impact of repairs increases the likelihood of breaks to neighboring valves. While the valves themselves are still in good condition, the bolts and other hardware holding them together are corroding. Stainless steel replacements for these items are on order and DPU water crews are putting other preventive measures in place to try to prevent additional leaks.
Meadow Lane manhole work
A new sewer manhole will be placed in the middle of Meadow Lane in front of St Joseph’s Church on Monday, May 20. This is a Los Alamos Public Schools project; however, DPU is overseeing this portion of the project. Drivers are reminded to slow down and move cautiously through the work zone.
Traffic & Streets Projects:
Los Alamos County Traffic & Streets Division staff manages the projects listed in this section. Please slow down and use caution within the construction work zones. Call Traffic and Streets Manager Daniel Blea with concerns at 505.663.8112.
