Low Volume Study | Parametrix
​Low Volume / Narrow Roadway Study 
​North Central Idaho
Client: ​​​​​​​​​Idaho Transportation Department

For this project, Parametrix developed long-range comprehensive corridor plans for 340 miles of state highway within ITD District 2. The effort involved 14 different state highways in Latah, Clearwater, Nez Perce, Lewis, and Idaho counties. The roads vary in functions, widths, and issues, but are generally characterized by low traffic volumes. The corridor plan addressed highway safety, roadway and bridge conditions, environmental resources and community values, as well as other issues identified by participants in the planning process.
