Public Works/Traffic Division projects:

Pothole Patching on Diamond Drive at Trinity/Canyon/Diamond intersections

Weather permitting, Traffic and Streets Division crews will continue to patch potholes on Diamond Drive on Thursday. Work will focus on the Diamond southbound lane at the intersection with Trinity and requires a short detour to accomplish the work. From 10:00 to 11:00 a.m. on Thursday, the left turn lane (east bound turn lane) on Diamond Drive that permits southbound vehicles to turn left onto Trinity will be closed for pothole repairs. The eastbound lane on west Trinity will also be closed and vehicles exiting Western Area will not be able to proceed through the Diamond intersection. Traffic will be detoured to Canyon Drive during this one-hour time frame. The northbound bike lane from LA Canyon (aka Omega) Bridge to Trinity Drive will be closed in order for crews to stage equipment for repairs during this time.

Once this work is completed, motorists should expect a moving single lane closure on Diamond as crews continue patching potholes between Orange Street near the high school and the San Ildefonso roundabout. Work will occur in the north and southbound lanes until crews run out of patching material.  Please allow extra time for possible delays, slow down, keep a safe distance from machinery, watch for road crews, and use extra caution when approaching these busy intersections at Trinity, Canyon, Diamond and Orange.

Diamond Drive Asphalt Paving Project

Additional testing will be performed to provide information that will be used in the Diamond Drive Project. Intermittent lane closures will take place on Thursday and Friday from 8:00 a.m. – 5:00 p.m.

Tsikumu Village - Road Improvements

Albuquerque Asphalt is currently working with installation of new ADA curb ramps at the intersection of San Ildefonso Rd and Sioux. Traffic Controls are in place for this work. Albuquerque Asphalt will start milling operation of the existing asphalt surface. They will overlay new asphalt starting at Ute and Yuma Street and begin work at 1450 Sioux Street with plans for pavement to be completed near 1220 Sioux Street by the end of the week.  To clear the street for this work, residents in this area are asked to please move all vehicles from their street during work activities Monday – Friday from 8:00 a.m. – 5:00 p.m. In addition, crews will continue working at various location with installation of valley gutters, replacement of extremely damaged side walk and curb and gutter and drive pad, and installation of new fillets, and ADA curb ramps at designated locations on these streets: Sioux, Cheyenne, Seminole, Iroquois, Yuma and Ute. Access to residences as well as mail/package delivery, emergency services, trash/recycle/yard waste pick-up will be maintained.

Other road construction projects:

NM502 Roundabout and Road Reconstruction (NMDOT project)

Star Paving will continue working on placing detour pavement on the north side of NM502 (Eastern area residential/airport side) and along the west shoulder of 4th Street to Central Avenue. During detour paving, flagging operations will be in effect Monday – Friday from 9:00 a.m. – 4:30 p.m. and traffic may be stopped for short durations for one lane passage through the work zone.

Traffic advisories from NMDOT are available on www.nmroads.com 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)

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 Rd 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 Rd, as this area is in close proximity to the NM502 Road Reconstruction project.

About this page...

This page provides citizens with basic information on County and non-County road construction projects. We are maintaining the page in the interest of keeping our citizens, visitors and commuters informed as a public service with one landing page where all information or links to information can be found.


About the Cone Zone...
The weekly Cone Zone report is posted here at the top of the page on Friday afternoons from March 8 through November 15, 2019, and then again from March through November 2020, in order to support public outreach especially for the NM502 Roundabout project, which is being constructed by the State of New Mexico's Department of Transportation over two construction seasons in Los Alamos.
 


More about the State of NM DOT's NM502 Reconstruction & Roundabout Project...

Here is a project map showing projects in the area of NM502 and the roundabout/near DP Road which may cause additional traffic congestion heading into the busy summer months. Motorists are asked to use caution in this area. Staging for the equipment and infrastructure needed for the NM502 project (a fenced, secure area for Star Paving) is located on DP Road, as shown on this map.

Here is a project drawing showing what the NM502 Roundabout will look like when completed (furnished to the County by the State of NM DOT)

Due to utilities conflicts along NM502 for the new roundabout to be constructed, new storm sewer, retaining walls and grade changes associated with the new road design, infrastructure for water, sewer, electric, natural gas and fiber optics will be replaced and relocated as follows:

• Replace and relocate 2000 feet of water transmission line
• Replace and relocate 4500 feet of water distribution lines, including all service connections and fire hydrants in the corridor
• Replace and relocate 4000 feet of natural gas lines including all services lines in the corridor
• Replace and relocate 350 feet of sewer lines
• Replace and relocate 5000 feet of underground electric lines, including duct banks, conductors, transformers, vaults and all service connections in the corridor
• Replace and relocate 1400 feet of the fiber optic systems owned by Los alamos County and Comcast

Here is a link to the NMDOT webpage for all District 5 Proposed and Active Projects with additional information from the State. Scroll past all Proposed projects to the bottom of the page where you will see NM502 listed as an Active project. The State has posted additional information about roundabouts on this page, along with the March 20, 2019 public meeting presentation. The presentation shows many aspects and views of the construction project and detours that can be anticipated as it proceeds over the next two years. 

Nearby projects:
N3B - TA-21 Clean Up
N3B and their contractor will be working this year and next year on an environmental remediation/clean up project at the former TA-21 site (far eastern edge of DP Rd).

Here is a Fact Sheet about that N3B project which involves hauling away non-radioactive or low-level waste after properly packaging it in containers.

Infrastructure for Bethel Housing Developments - installation on or along DP Road:
Bethel Development's “Canyon Walk” apartments will be starting infrastructure and construction of new affordable workforce housing, scheduled to begin August 2019 with completion by August 2020. A second housing project by Bethel called “The Bluffs” on DP Road is also being considered and work could begin for additional Senior Housing. Both of these sites are referenced in the main NM502 project map shown above.

Future DP Road Infrastructure (long-term County project)
The County could begin installing infrastructure for the DP Road area in the future, as more land parcels become available and after TA-21 remediation is completed. These parcels are part of DOE Land Transfers that could be used for future light industrial or residential development. The infrastructure would extend to the TA-21 site as a "spine" for future development on the north and south side of the road. DP Road needs to be upgraded to include basic infrastructure that could be used by existing or new businesses or homes. For example, there is currently no sewer line in this area. The County applied for grant funding last year for offsetting these types of infrastructure costs for the DP Road project, but it was not approved.


What else do I need to know?

The County is working on "Frequently Asked Questions" about the projects occurring in the vicinity of NM502/DP Road. Watch for that document to be posted as a PDF here on the webpage later in April.

Links to other entity websites for projects will be featured here for convenience as they become available.

For general questions about construction, you may call the Customer Care Center at 505-662-8333 and a representative will direct your call to the appropriate office. 

For feedback on this webpage, send an e-mail to the webpage administrator.



What's next? A note about planned or possible future road projects:

Below is a listing of projects that motorists WILL or MIGHT see occurring in Los Alamos that might further impact NM502/Trinity Drive:

Diamond Drive (updated status on March 29, 2019):

Reconstruction of the road from Trinity Drive to the San Ildefonso roundabout by the Golf Course is set to occur this summer. In March, the County applied for emergency funds for road reconstruction after several harsh winter snow events in December and January severely damaged Diamond Drive. Temporary asphalt repair and patching is underway, but it is not intended to be a long-term fix for Diamond Drive. Public Works has budgeted its own road repair funds in FY20 (starting July 1, 2019) to accomplish this reconstruction project, even if emergency funds are not received from the State and Federal government.

Canyon Rim Trail Underpass:

An underpass to connect LA Mesa trail underneath NM502 and south to the Canyon Rim Trailhead is at the design stage and may begin construction Spring 2020. It is located further east from the NM502 project. 

Work in Los Alamos on various projects by the County or by others may get underway in 2019 or 2020 that might cause some traffic slow-downs:

Trinity Drive:
There could be several projects occurring over the next two years while NM502 is under construction at the eastern edge of Los Alamos:

Construction on new businesses/buildings at the 20th Street lot 

Traffic light installation at 20th and Trinity Drive once new businesses are constructed.

Changes to Trinity Drive near the LA Medical Center for better access to the former DOE/LASO site where new apartments known as "The Hill" are approved to be built

New business construction along Trinity Drive (Natural Grocer is expected to build a store at the Shriner's Club lot)


SR4/Truck Route intersection:
This has been a high-profile project for several years - there are design plans in progress but no funding set aside for construction. At this time, and because of the impact that will already occur for increased traffic on SR4/Truck Route during the NM502 project for two years, it is not anticipated that there would be road work on the intersection at the same time.

Watch for updates on this page for Future Projects such as the ones listed above, or, for new projects to be added as they are identified. As the County gets more details, updates will be posted here.


SHOW YOUR SUPPORT, LOS ALAMOS!
Construction can be difficult and present special challenges for businesses caught in the construction zones and related/adjacent areas. Motorists tend to avoid orange barrel zones and this can have significant economic impacts on businesses. Los Alamos has many small, locally-owned and operated restaurants, specialty shops and stores on the eastern edge of Los Alamos. The County encourages residents and visitors to support local businesses, especially those on DP Road, which will likely be impacted by the construction. Other businesses at Entrada Business Park, East Gate, along Trinity/Knecht (Mari Mac and Smith's Marketplace and further west on Trinity) as well as those on Central Avenue may likely be impacted, too. The County is working with MainStreet and the Chamber of Commerce to find ways to mitigate impacts and support them, but your help is urgently needed! Allow extra time for patronizing these businesses, but please don't shy away just because of construction! They need your help to continue to operate all of your favorite and valued restaurants, shops and other small businesses to be able to provide you great products and services.
