Diamond Drive near Golf Course
Starting Monday, July 30, after the morning commute, traffic control will be in place on Diamond Drive in the vicinity of the Golf Course to repair a leaking irrigation line. The outside lanes of both northbound and southbound traffic will be closed and the bike lanes will be shifted inwards to provide a safe work zone for shoulder work. Minimal delays may be experienced.
Pavement Preservation Program
Crews will be working to finish on Azure, and then moving to Aragon west of Rover, followed by Barcelona and Cañada Way. Flyers will be distributed 48 hours in advance of work beginning in the immediate area. Once construction gets to your area, please ensure that all vehicles are parked off-street. Expect flagging operations, minor delays, and typical construction activity.
Other White Rock streets included in this year’s program include Cañada Way, Barcelona, Rover from Carlsbad to Grand Canyon. In Los Alamos – Range Road and North Mesa Road from Hawk Drive to just east of the Posse Lodge. If you live on any of these streets, please watch for your 48 hour notice.
Eastern Area 2 Concrete, Paving & Utility Project – Phase 1
Canyon Road between East Road (NM502) and the Myrtle Green has been closed to through traffic. Residential access to this area will be maintained; however, residents who park on Canyon Road are asked to park off-street or on a nearby side street. Residents can expect flagging operations on Canyon Road during the day time, and two-way traffic at night. Minor delays may be experienced. All through traffic must seek alternate routes.
15th Street between Central and Trinity is closed to through traffic with flagging access to area businesses. Pedestrians in the area need to stay out of the construction zone. Expect intermittent flagging operations throughout this section of 15th to allow trucks and heavy equipment to access the work area. Motorists are urged to use 20th Street or Knecht Street as alternative routes.
4th Street between Central and Canyon continues to be closed to through traffic. Residential access will be maintained.
Work has started on Myrtle between 9th Street and 15th Street. This section of Myrtle is closed to through traffic with flagging operations during the day and two-way traffic at night.
NM4 Improvements Project
Expect striping operations and roadway marking installation to start on Monday. The striping operations occur with at least one shadow vehicle following the striper to allow adequate time for the roadway paint to dry and to prevent traffic from crossing the wet paint. Please do not try to get in front of the shadow vehicles. Intermittent lane closures can be expected when the contractor installs roadway markings such as turn arrows or stop bars. Until the permanent signs are posted, the speed limit within the construction area is 30 mph. Please drive defensively and watch for construction vehicles.
NMDOT Chip Seal Project on N.M. 4 between White Rock and Sandoval County Line
Bicyclists riding in the vicinity of N.M. 4 and N.M. 501 are urged to use extra caution during chip seal work being done by the NM Department of Transportation. The chip seal work continues with completion anticipated on Aug. 3, depending on weather. There may be delays between the hours of 5 a.m. to 4 p.m. as well as single lane closures with a flagging operation and pilot car escort. A spokesman for NMDOT said bicycling through the work zone is “highly discouraged” due to the oily surface, loose gravel, and heavy truck traffic.
NMDOT Curb & Gutter Remove/Replace Project on Trinity Drive
Los Alamos County has been informed that the State of New Mexico may have crews in Los Alamos late next week and the following week in order to remove and replace crumbling and damaged curb and gutters that exist along east- and west-bound Trinity Drive. This would result in rolling lane drops around the work zones and could cause some delays for commuters if work occurs during peak traffic times morning, noon and evening.
For more information on the above, contact NMDOT-District 5 Maintenance Supervisor David Martinez at (505) 476-4202 or Patricia Wolff, Public Information Officer at (505) 476-4245.
West Road Closed Due to Potential Flooding
Due to safety concerns related to potential flash flooding in the canyon, LANL and the County have closed West Road until the monsoon season is over.
