Porcupine Bay Road Landslide – Public Works Skip to content

Porcupine Bay Road Landslide

The landslide occurred on April 2, 2017.  The road has been closed since then and will be until further notice.  Due to public safety and the location of the landslide, there will not be a temporary bypass or detour constructed at this time.  The slide is not very active at this time but there is still some material sloughing off on occasion due to the nature of the slide and the type of soils that are out there.

  Lincoln County has given the contractor, Condon-Johnson & Associates, Inc. (CJA) the notice to proceed. The contract time will begin on June 4, 2018.  They will have 105 working days to complete the project. 105 working days will be at the end of October.

The Porcupine Bay Road will be closed to all traffic during the construction of this repair process.

For those of you that want to see the construction and what is going on, do so from a distance.  Please do not go into the construction area due to safety reasons.  It will be clearly marked.  We will be updating this page with photos throughout the project.  So check back frequently!
