Seven-Month Road And Utility Improvements Construction To Begin Soon For 33rd/34th And Arkansas


Los Alamos County Public Works has contracted with TLC Plumbing and Utilities to begin a major utility, storm drain, and road improvements project on the 33rd/34th Street loop in the Aspen School neighborhood, and Arkansas Avenue between Diamond Drive and 41st Street in the North Community. This information was also presented at the Public Meeting conducted during the regularly scheduled Transportation Board Meeting in January.  

This seven-month project will begin March 27 for the 33rd/34th Street Loop, and April 17 for Arkansas Avenue. The anticipated completion date for the project is October 2023. 


The project scope includes removing existing asphalt surface and base material, installing new water lines and storm drains, reconstructing, and upgrading existing sewer lines, compacting subgrade and base material, and installing new asphalt. In addition, crews will be rehabilitating a 10-inch sewer line located in the backyards of homes fronting 35th Street using a spiral PVC lining to avoid trenching. Reconstruction of driveways, sidewalks, curb ramps, fillets, and curb and gutters will be completed as needed. 

Construction Area:

Work will begin on the 33rd/34th Street loop, commencing on 33rd Street, 550 feet south of the Villa intersection (in front of Aspen Elementary School), and continue northwards to the top of the loop before heading southwards on 34th Street back to Villa. 

As this work continues, a second crew will begin construction on Arkansas Avenue near Diamond Drive, moving northwest to the 41st Street intersection. 


TLC crews will work in both areas from 7 a.m. to 5 p.m., Monday through Friday and will be primarily in the roadway. 

Traffic Impact:

To minimize disruption, TLC crews will notify and coordinate with affected residents on certain construction logistics, such as parking restrictions or temporary water shutoffs. They will also ensure ingress and egress to residents’ homes as much as possible. In addition, services such as mail delivery, trash and recycling collection, school bus, and emergency services will always be maintained.  Residents can expect large equipment, construction noise, some disruption of water services with advance notification, during hours of operation, dust abatement will be performed regularly. Motorists and pedestrians are advised to use caution around construction activities and avoid entering the work zone. The road will be closed to through traffic but open to residents.
