Open-Graded Friction Course Work Control in Diamond Drive Construction Zone: Please Read

From the county. Thanks for reading.

Late next week (Thurs – Sat), AS Horner will begin placing Open Graded Friction Course (OGFC) on Diamond and at the intersections between south of Sycamore and the Los Alamos Canyon Bridge abutment. Traffic control will be very fluid as the process moves relatively quickly unless there is rain. As work is done in the intersections, there will be delays and traffic will be rerouted with advance traffic control signs.  The following week, OGFC will be placed on Diamond Drive, which will mostly be accomplished with lane drops except for when the laydown machine crosses intersections – then there will be intersection delays and traffic will be rerouted depending on the intersection. We will have police officers and flaggers on site to assist travelers, but it is going to be a difficult and likely frustrating process for all users. Once we get to the mainline, we will be starting after 8:30 a.m. and will be placing OGFC in the opposite travel direction of peak volume traffic.

The reason I am asking for your help is that it will be imperative that motorists, bicyclists, and pedestrians stay out of the paving operations work zones and stay off the OGFC until it has cooled and the work zone is removed. Any  shortcuts through an active work zone will likely result in some level of damage as OGFC is a 5/8” layer of very hot and sticky substance that will adhere to or stain just about everything, but will certainly stick to tires and shoes (as well as paws). If the weather cooperates, we are anticipating that the OGFC application will be completed before Sept 2.

We’ve put this information out for Sunday’s cone zone and I’ll be posting it on the web shortly; however, if you could please send this info to your LA Bike and LA Walks distribution groups I’d really appreciate it. Please copy me on what you send out for my public outreach files. If you have any questions, please let me know and thanks in advance for your help!

FYI, I will also include this info in my weekly Road Conditions distribution that includes LANL PIO, so I will ask Steve Sandoval to include something in the LANL daily newsletter as well.

Looks like the first layer is down (left turn from southbound Diamond to Canyon). This is a pretty thick layer so look out for the step-up between lanes.
