The Cone Zone: Week of Aug. 19, 2019

Public Works/Traffic Division projects:

Diamond Dr Paving

Star Paving is wrapping up manhole adjustments and will be pulling the steel plates located on Diamond Drive between the Omega Bridge and the Sandia/Orange Intersection by early next week, completing this road work in front of the high school. Milling and paving operations from the Sandia/Orange intersection northbound continue during daytime hours Monday - Friday and may include Saturdays. Work in this area includes completion of manhole adjustments as well as applying striping and markings, which requires intermittent lane closures.  Striping and marking activities will take place daily as well as overnight to avoid impeding traffic as much as possible.  Motorists will continue to see daily lane drops for milling and paving operations in each direction as work advances past Sycamore and continues to proceed toward the golf course; allow extra time for delays, especially with schools back in session and early release times for the elementary schools occurring on Wednesdays, causing additional traffic congestion in these areas during the lunch hour.  

During daytime hours Monday through Friday, crews continue working between 8:30 a.m. to 4:00 p.m. to accommodate peak commuter times for travel. 

Final project completion is set for Sept. 27, weather permitting. 

Yucca & Arkansas: Continued Sidewalks Work 

Public Works crews continue replacing sidewalks at the intersection of Arkansas Ave and Yucca St. Vehicles and pedestrians are advised to follow all traffic control devices and slow down in the work zone. Work should be completed by Friday, August 23, weather permitting. 

NW Corner 33rd & Walnut: Handicap Ramp, Sidewalks Work 

Public Works crews began installing a handicap ramp at this corner on August 16. Flagging operations are in effect to assist traffic through the intersection.Vehicles and pedestrians are advised to follow all traffic control devices and slow down in the work zone. Work should be completed by August 26, weather permitting.

Other road construction projects: 

NM502 Roundabout and Road Reconstruction (NMDOT project)

Eastbound Detour CHANGE Begins Monday, Aug. 19: Star Paving plans to close Trinity Drive between DP Rd and Central Ave beginning Monday, Aug. 19 for two weeks. This closure is needed to facilitate the crossing of water, sewer, gas and numerous electrical and communications conduits. Eastbound traffic will be detoured from Trinity Drive onto 15th St and then onto Central Ave.  

Access to DP Rd and all businesses on Trinity Drive between 15th Street and DP Rd will be maintained throughout the closure. All traffic exiting DP Rd will be required to turn left onto Trinity Drive and use the appropriate detour routes. Upon completion of the utility crossing, Eastbound traffic will return to the current detour which is 4th St. to Central Ave and back onto Trinity Drive. 

Download a PDF of the map showing the detour here. 

No change to Westbound traffic; Westbound traffic will continue to use the current detour which is Central Ave to Knecht St. 

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. 

Sidewalk Closure: Canyon Rd near NM502 Roundabout Project: 

Megacomm Service LLC is finishing up their fiber project along the western side of Canyon Rd between the intersection of NM502 and Canyon Rd, near 4th Street and Canyon. Sidewalks continue to be closed; pedestrian traffic must divert to the East side of Canyon Rd. Work should be completed by Tuesday, August 20, weather permitting. 

TA-21 Clean Up Project - DP Road (N3B project):

No change in truck traffic on DP Rd from last week's report. 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 near the NM502 Road Reconstruction project. 

Advance Notice: Overnight Excavator Transport from DP Rd to Main Hill Rd (NM502) to Truck Rt to NM4 to Pajarito Rd - Move Set for Saturday, August 24

N3B will be transporting an excavator from TA-21 at the end of DP Rd to Trinity Drive, crossing Marimac Plaza's parking lot to Central Ave, then east down NM502 to the Truck Route, beginning at 6:00 a.m. Saturday, August 24. They will stop at the Truck Route Inspection Station for inspection, then resume transport after 8:00 a.m, traveling into White Rock on NM4 to Pajarito Rd. LAPD officers will be assisting on site to close NM502 at the bottom of the Main Hill Rd during these morning hours to allow the excavator to move safely down the Main Hill Rd to NM4 and the Truck Route Inspection Station. Early morning traffic should expect delays on Main Hill Rd and the Truck Route near the inspection station during this time frame of 6:00 a.m. to 8:00 a.m. on Saturday, August 24.  

A second move of two excavators is expected to occur in a similar traffic pattern on Saturday, Sept. 7. Because two excavators are being moved, the closure time may be longer. More details will follow in a future Cone Zone update.

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'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:

Canyon Rim Trail Underpass:
An underpass to connect LA Mesa trail underneath NM502 and south to the Canyon Rim Trailhead is wrapping up design stage and set to go to 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:
In June, the State DOT announced that they have secured funding to do much-needed roadway, curb and gutter repairs on Trinity Drive, from Diamond to the eastern edge of Los Alamos. Work could get underway in August or September; we are awaiting further updates from the State. A portion of the work would involve a "road diet" near the turn off to the former LASO building site (now expected to become The Hill apartments with construction beginning soon.)

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 a new business set to occur at the 20th Street (all six pads) lot - to be announced in August

Traffic light installation at 20th and Trinity Drive once the new business listed above is constructed.

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.
