Pajarito road is currently impassible by bike due to fresh oil sprayed from edge to edge. Same thing appears to be happening on E/W Jemez in neighborhood of TA-3.
Here is more from LANL.
A LANL road project currently is in progress and is expected to be complete by Friday, Sept. 18. The Laboratory's main arterial road surfaces are being treated with an asphalt emulsion intended to extend the service life of the pavement. The following road sections will be worked on this week from 9 a.m. to 3 p.m.:
- East Jemez (Truck Route) from NM 4 to the Omega Canyon Bridge
- West Jemez from West Jemez to NM 4
- Pajarito Road from Diamond Drive to NM 4.
The treatment sets up and road surfaces are drivable within 20 minutes. Traffic control will be in place as sections are treated. Motorists should expect delays and are asked not to drive on treated areas until traffic-control personnel direct them to do so.
Once dry, the road is fine to bike on. --KJS
