General Description:
The West Bench Circulation Study evaluated both 3-lane and 5-lane roadway alternatives for Cloverdale Road, Five Mile Road and Maple Grove Road, generally between Chinden and Fairview. These roadway segments are currently planned as 5-lane facilities in the ACHD Capital Improvements Plan and other planning documents. This study evaluated the feasibility of constraining these segments to 3-lanes.
Initially, Cloverdale Road was being considered for expansion to 5 lanes along a 4.5 mile stretch, however, during the concept design process, it was determined that a 3-lane roadway from DeMeyer to just north of Fairview may be able handle the traffic volumes. The need for 5 lanes was based on the ACHD Capital Improvements Plan and Communities in Motion, a long-range transportation planning document established by the Community Planning Association of Southwest Idaho (COMPASS.) The Transportation Land Use Integration Plan (TLIP) process suggests ACHD should evaluate a 3-lane option for this segment.
This study concluded the following:
When these segments of Five Mile Road or Maple Grove Road become closer to being programmed, it is recommended that it be reevaluated which has the priority of needing 5-lanes. If the property along Maple Grove Road experiences a significant amount of redevelopment, it may make sense to rebuild it to 5- lanes because it has a higer travel demand.
