Project Update #4

Wednesday, May 20, 2015

LEE VINING ROCKFALL SAFETY PROJECT

Timeline:

  • Rock scaling is complete at slope #6 (the northernmost slope).
  • Test anchors have been successfully drilled on slope #6. The anchors will hold the anchored mesh and cable mesh in place.
  • Production anchors are now being drilled on slope #6.
  • Rock scaling on slope #5 (just to the south of slope #6) is scheduled for next week.
  • Rock scaling and slope cornice rounding on slope #2 (second closest project slope to Lee Vining) is scheduled for next week.
  • Traffic signal timing has been fine-tuned to reduce delays.
  • No 1-hour closures are currently scheduled. As soon as more specific information on these closures is available another project update will be distributed.
  • Construction began May 4 and is planned to continue through fall 2015. Construction may also be required in spring/summer 2016.
  • 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.
  • In addition to the standard up-to-20 minute delays, for several weeks during construction there may be
    1 hour full closures, from 6 am to 7 am.

 

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.
