The Interstate 80-Gilman Street interchange construction was completed in 2025 after extensive planning beginning over a decade ago. The $100 million project included two new roundabouts designed to mitigate congestion and enhance safety for motorists, cyclists, and pedestrians alike. The previous layout was associated with high collision rates and confusion regarding right-of-way. Officials expect the revamped interchange, alongside a new bicycle and pedestrian overpass, to reduce crashes and improve traffic flow while addressing safety concerns identified over the years.
