Project Update #6

Thursday, July 9, 2015

Project Purpose:

  • The project purpose is to minimize the rockfall from six cut slopes north of Lee Vining near Mono Lake to improve safety. The project includes a plant establishment program on all slopes to reduce erosion, establish healthy soil, and promote successful revegetation.
  • In addition, three of the slopes will receive anchored mesh to stabilize the slopes and reduce rockfall.

Timeline:

  • Slope #1 and slope #2 – work complete
  • Slope #5
    • Rock scaling is complete. Test anchors have been successfully drilled and tested.  The anchors will hold the anchored mesh and cable mesh in place.
    • Production anchor drilling is expected to be complete this week. In total, over 3,000 anchors are needed on the project.  For the northern portion of this slope the anchor work is complete and erosion control work is in progress.
    • Once all anchors have been drilled, erosion control work will begin in phases on the remaining slope, then the anchored mesh and cable netting will be installed.
  • Slope #6
    • The anchored mesh and cable netting has been placed.
    • Workers are now tightening the fasteners and contouring the mesh and netting to the slope.
    • The lower 8-10 feet will receive erosion control, then the mesh and netting will be fastened and contoured to this part of the slope.

Road Closures:

  • 1-hour closures have not been scheduled. As soon as more specific information on these closures is available another project update will be distributed.  1-hour full closures will be from 6 am to 7 am.
  • Delays during construction will mostly be standard up-to-20 minute delays with one-way reversing traffic control. The temporary signal uses detection technology to minimize delays.

Construction began May 4 and is planned to continue through fall 2015.  Construction may also be required in spring/summer 2016.
