About this file
These are traffic control plan diagrams for logging operations and road work at Sandia Crest Scenic Highway in New Mexico, designed by the USDA Forest Service. The plans detail temporary traffic management and safety measures for work zones affecting NM-14, NM-536, NM-306, NM-165, and CR-488.
The first plan (TCP Index #069141) establishes work zone signage and channelization for multiple road segments with 500-foot spacing intervals between warning signs. The plan specifies "Road Closed to Thru Traffic," "Logging Operations Ahead," "Road Work," and "Be Prepared to Stop" signs positioned along the highways and connecting roads near the 10K Trailhead. Tangent device spacing is limited to not exceed 50 feet, and the posted speed limit is 25 MPH. The second plan (TCP Index #069142) covers the CR-488 area and specifies an equipment staging area where the contractor must maintain helipad access at all times, with "Road Closed" and "Log Trucks Entering Road" signage. Both plans were designed by Gabriel Chavez on 12/04/25 and include notes that adjustments to sign spacing and channelization devices shall be made in field based on vertical and horizontal curves, side roads, and driveways. All advanced warning signs should be double-indicated when feasible, and existing speed limit signs must be covered if speed limits are reduced.
