Highway 75 Redesign

Our Highway 75 corridor serves as part of the US highway system and as our main street.


We want a corridor that will safely serve our community and visitors, offer safe pedestrian use and welcome travelers to our thriving community.

We are working with the Iowa DOT on a design that would change Highway 75 in Sioux Center to an enhanced 4-lane roadway.

This design features two lanes of travel in each direction with medians and a center turn lane. 

Construction is slated for 2023-24, with project completion set for 2025.

Designed for safety

Landscaped medians calm traffic and create a safe zone for pedestrians crossing the street. They can also decrease the number of conflict points where traffic turns.

Effective & Accessible

Two lanes will help traffic flow and allow for more space between vehicles for safety and for turning traffic.
