Bold statement: A new roundabout at Birch Street and South Boulevard could reshape how Idaho Falls drivers move—and the community is weighing in before construction begins. But here’s where it gets controversial: does a three-approach roundabout truly improve safety and daily commutes, or will it disrupt nearby businesses and routine trips? Let’s break down what happened and what it could mean for residents.
Idaho Falls residents attended an open house inside the City Council chambers on Wednesday evening to learn how the proposed roundabout would function. Toy cars were brought in to demonstrate traffic flow, turning dynamics, and the overall feel of navigating the intersection once the roundabout is in place. City Engineer Jon Knowles reported predominantly positive feedback from attendees.
Knowles explained that the goal of the session was to help people understand that roundabouts can be a strong option for this type of intersection. The Birch Street–South Boulevard junction currently operates with a stop sign on Birch Street, but the area experiences heavy traffic around 5 p.m. and has a history of crashes according to local reports.
He described a common scenario today: a driver on Birch Street waits for a gap in South Boulevard traffic, grows impatient, and makes a risky move into traffic. Meanwhile, South Boulevard traffic can be moving faster than ideal as people hurry to get home. The roundabout, with its three approaches, is designed to reduce the number of conflict points—locations where a crash could occur—compared with a traditional stop-sign setup. In a three-approach setup, nine potential conflict points exist; the roundabout reduces this to six, according to Knowles. He also noted that the slowed speeds required to maneuver through a roundabout generally lessen crash severity.
City of Idaho Falls staff are collecting ongoing feedback on the project. Knowles indicated that the plan can still be tweaked and encouraged people who couldn’t attend to email their comments to ifeng@idahofalls.gov. After completion, new medians on Birch Street and South Boulevard will restrict left turns from certain access points (an alley, 6th Street, and North Ridge Ave). Motorists will need to adjust by traveling around the roundabout and continuing toward their original destination, sometimes via right turns.
Attendees shared personal reflections. Mya James and Mike Quinn, residents nearby, attended to see how changes would affect their daily routines. They felt their questions were answered and described the roundabout as promising, with one noting that traffic would remain open in both directions through most of the project—their main concern.
James echoed a similar sentiment, adding that the changes shouldn’t severely disrupt daily commutes. Canon Browning, who visits the area every day for school and who attends partly for a government class, acknowledged concerns about how the medians might affect access for nearby daycare centers and businesses. Still, he believed the project would be manageable and that he would benefit from easier access to school. Browning summed up his view: the idea seems sound and worth implementing.
