NM502 Roundabout & Road Reconstruction (re-posted press release from NMDOT)
New Mexico Department of Transportation(NMDOT) and Star Paving Company will begin roadway reconstruction on NM 502 from mile post 1.257 to mile post 2.053 in Los Alamos.  The contractor will begin construction and preparation for detour paving. 

Starting this week - NM 502 will be reduced to one lane in each direction.  Motorists can expect minor delays from 7:00 a.m. to 5:00 p.m. Monday thru Friday and short duration temporary closures during non-peak hours at the east end of the project in the existing 2-lane section of the roadway using flagging operation.   

This project will improve NM 502 through Los Alamos between Knecht Street and Tewa Loop for a total project length of 0.8 miles. This project will include roadway reconstruction, earthwork, curb and gutter, sidewalk, concrete retaining walls, storm drain, landscaping, permanent signing, lighting, traffic signalizations, and utilities.  The project will also replace the existing intersection at NM 502 and Central Avenue with a roundabout to improve traffic flow through Los Alamos.   

The project cost is $10.8 million. This is a 350 working day project.  Project is anticipated to be completed Winter of 2020; weather permitting. Star Paving Company out of Albuquerque, New Mexico is the contractor for the project.   

Traffic Advisories and updates on this project will be posted on the New Mexico Department of Transportation's road conditions website, http://nmroads.com/

NOTE: NMDOT has RE-SET the public meeting about the project that had to be canceled last week due to inclement weather. The meeting will be Wednesday, March 20 at 5:00 p.m. at Fuller Lodge (Pajarito Rm). The public is welcome to attend.

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. If you don't want to bookmark and visit this page on Fridays, you can sign up to receive the Cone Zone report in your e-mail in-box - link to Subscribe to Newsletters here.


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

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 March.

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.

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

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

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 (new Starbucks)

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 expected to be built

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

Diamond Drive:
Reconstruction of the road from Trinity Drive to the San Ildefonso roundabout by the Golf Course could occur. The County has applied for emergency funds for road repairs after several harsh winter snow events in December and January damaged Diamond Drive. Temporary asphalt repair is underway, but it is not intended to be a long-term fix for Diamond Drive. Work on Diamond to repave the road could get underway this summer if funded.

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.
