Montana Department of Transportation’s Broadus Interchange Project represents a community-driven solution to reduce traffic congestion, while improving operation and safety of the existing I-94 interchange.
Construction began in spring 2019 and was completed in November 2020. Eastbound and westbound bridges crossing South Haynes Avenue were demolished and reconstructed to increase capacity and bring them up to current design standards, and two roundabouts were constructed at the ramp termini.
The south roundabout is the first five-legged roundabout constructed by MDT to perpetuate the Steel Street intersection with Haynes Avenue — a design solution that prioritized safety while minimizing impacts to area business owners. Roundabouts are proven to effectively reduce traffic congestion and improve safety, making them part of MDT’s engineering emphasis of the Vision Zero goal: zero deaths and zero serious injuries on Montana roadways.
In September, a horse statue commissioned by the City from local sculptor Erin Thormodsgard was installed at the center of the roundabout, standing as a fitting symbol of the importance of this project and the growing community the new interchange will serve for years to come.
