Conway Ranch Shoulder Widening Project

The Project:

The Conway Ranch Shoulder Widening project proposes to widen the existing paved shoulders on US 395 from postmile 57.7-60.7. It also proposes to install shoulder rumble strips, correct a substandard compound curve and lengthen the chain control area at postmile 59.49 by 500 feet. Culverts will be extended or replaced as needed. There are currently two “build” alternatives under consideration for the project.

  1. This alternative proposes to shift the highway alignment to the west and only widen pavement to the west to allow for standard 8ft shoulders on both sides of the highway. This alternative will require approximately 0.5 acre of new right-of-way easement to be acquired from Mono County.
  2. Alternative 2 proposes to widen the pavement on both sides of the highway (east and west) to provide standard 8ft shoulders. This alternative will require approximately 2.07 acres of new right-of-way easements to be acquired from Mono County, LADWP, and BLM.


This project is proposed to increase roadway safety and reduce the number of run off the road collisions in the project area. This segment of US 395 has a total accident rate 3.87 times greater than the statewide average.
