The Idaho Transportation Department will activate the new, long anticipated, interim traffic signal at the intersection of State Highway 55 and Banks Lowman Road on May 5, introducing a new traffic pattern to improve safety and efficiency at this busy junction.
This week crews will finish installing the traffic signal poles, with final preparations scheduled over the coming days to ready the intersection for the signal to go live. Once operational, the signal will provide safer and more predictable turning opportunities—particularly for those traveling from Banks Lowman Road onto SH-55, where long wait times have been common, especially during weekends and peak summer traffic. This interim signal solution was developed based on a preliminary study and public feedback. ITD crews designed this important safety project and installation work has included building the signal foundations, placing underground utilities, paving on Banks Lowman Road, installing guardrail, and erecting signal arms and heads.
“The new signal will help mobility and safety at this historically busy summer SH-55 river access intersection,” said Dan McElhinney, ITD Chief Deputy and Chief Operations Officer. “This signal will provide a turning solution for those drivers on Banks Lowman Road, which will help reduce long lines and delays.”
In addition to adding the interim signal this year, ITD is also working on a long-term intersection widening solution. Staff has already begun 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.
