June 25, 2006: This picture looking north on US 59, which includes a wrong-way triplex with US 30 and IA 141, approaches the north intersection with US 30. More pictures can be seen on the IA 39 page.
The Iowa Department of Transportation has put two intersections in Denison on its bucket list.
A public meeting tonight in Denison will put on display the plans for turning both of US 59’s intersections with US 30 into roundabouts. These three-way intersections, which haven’t changed since they were built in the early 1960s, have complicated geometries. Admittedly, that makes them ideal candidates for roundabouts.
According to plans on the page, the core of the “South Bucket” will be just a hair north of the present intersection, and the core of the “Middle Bucket” will be just a hair south of the present intersection. This terminology implies the “North Bucket” is the US 59/IA 39 intersection, which is untouched in this project.
Overall construction also includes replacing the bridges across the Union Pacific Railroad. It will be a three-year project, starting in late 2028 and ending in late 2031.
