ITD begins installation of interim traffic signal at the intersection of SH-55 and Banks Lowman Road
BANKS – The Idaho Transportation Department will begin construction on an interim traffic signal at the intersection of State Highway 55 and Banks Lowman Road tomorrow to provide safe turning opportunities.
Historically traffic on Banks Lowman Road has been unable to find sufficient gaps in the steady southbound traffic on SH-55, resulting in long lines of drivers waiting especially on weekends. The signal was identified as the best solution based on a preliminary study of options and public feedback. It will save turning drivers' time, and the intersection will no longer require flaggers to safely operate during peak traffic in the summer.
This week crews will begin constructing the foundation for the traffic signal, followed by installing utilities at the intersection. Additional work includes the installation of signal poles and arms, signal heads, minor paving on Banks-Lowman Road, and guardrail installation. The traffic signal project is expected to be complete by summer.
ITD maintenance forces will manage traffic during this project, utilizing alternating lane closures and flaggers during some phases of the work. Travelers are encouraged to check 511.idaho.gov and plan for delays in work zones like this one, as all closures will be posted.
In addition to adding the interim signal this year, ITD is also working on a long-term intersection widening solution. This year ITD will begin a comprehensive intersection planning and design process that will review bridge widening, hillside setback earthwork and turn lanes to meet the growing regional and river area traffic mobility demands. The design and public outreach process will take multiple years.
