Purple Sage/Beacon Light Alignment Study

General Description

On June 25, 2008 the Ada County Highway District Commissioners adopted the Purple Sage/Beacon Light Alignment Study, including Alignment A as the preferred alignment.

Purple Sage/Beacon Light Alignment Study Report

Staff Report

  • ACHD is seeking comments on a study that will determine alignment options to extend Beacon Light Road west to Purple Sage Road in Canyon County. The study will also determine the type of roadway section and whether or not it will include curb, gutter and pedestrian/bicycle facilities.
  • Once a proposed alignment and road width has been identified, ACHD can start preserving the right-of-way as the area grows.
  • ACHD anticipates that the proposed roadway will be at least three lanes, if not five, depending on the amount of growth this area sees.
  • Construction of any proposed roadway would occur in increments as adjoining properties develop.

Background

  • The need for the Purple Sage/Beacon Light connection was identified in the April 2006 draft of the Communities in Motion (CIM) long-range transportation plan for Ada and Canyon counties as a potential congestion reliever for SH 44 in the future.
  • CIM proposed three improvements to the Purple Sage/Beacon Light corridor between I-84 and SH 55:
    •  Widen Beacon Light from SH 55 to SH 16 to four/five lanes.
    • Connect Purple Sage and Beacon Light.
    • Widen Purple Sage to three lanes from the proposed connection to I-84.

Communities in Motion (CIM)

  • CIM is the long-range transportation plan developed by the Community Planning Association of Southwest Idaho (COMPASS) to address transportation issues expected in the next twenty or more years.
