Snake River Crossing Project Draft Purpose & Need

Purpose & Need statements are used to develop, evaluate, and guide the decision-making process. ITD encourages community and agency input in developing the proposed Purpose & Need of a project:
 

  • The purpose as to why improvements are being proposed
     

  • The transportation needs to be addressed and the underlying causes of the problems

PURPOSE
 

  • Enhance local and regional mobility by alleviating congestion along the U.S. Highway 93 corridor, generally from US-30 to I-84
     

  • Improve safety
     

  • Provide a redundant crossing of the Snake River

NEED

​

  • Many intersections along U.S. Highway 93 and in the study area experience delay, and conditions are anticipated to worsen by 2050 as the area continues to grow
     

  • The study area experiences a large volume of crashes, with the highest vehicle crash rates in the study area occurring along US-93/Pole Line Road, Blue Lakes Boulevard, and Eastland Drive 
     

  • Heavy vehicle traffic is projected to account for 24% of daily traffic by 2050 on most major corridors in the project area, and freight mobility is critical to accessing agriculture and manufacturing businesses
     

  • The US-93 Perrine Bridge is the primary connection between I-84 and Twin Falls, and an additional crossing would provide redundancy in the roadway network

Goals created early in the study process were presented to agency and community workshops. The feedback we received on these goals and objectives was used to help develop the draft Purpose & Need statement.
