HIGHWAY 75 REDESIGN
We're rebuilding a roadway to safely serve our community and visitors, offer safe pedestrian use and welcome travelers to our thriving community.
We are working with the Iowa DOT to rebuild Highway 75 in Sioux Center as 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 2023-25, with project completion set for 2026.
Phase 1 - 20th Street to 13th Street South
- April – Highway traffic (northbound and southbound) shifts to east side of existing highway pavement from 20th St. to 13th St. S. and construction begins on the west side. Utility work also begins. Construction will be staged to allow for two-direction traffic (one lane each way) through most of the work and to maintain at least one access to the businesses in the Walmart area throughout construction.
- Mid-Summer– Newly-paved 13th Street S. and 2nd Ave. S. opens. Work on 16th Street S. begins.
- Fall – Highway 75 traffic shifts to new west side pavement. Work begins on east side.
- Late fall – Paving east side of Highway 75.
- Spring 2024 – Median paving and landscaping.
Estimated schedule depends on weather.
Regular work schedule will be Monday through Friday, 7 a.m. to 7 p.m.
Phase 2 - 13th Street South to 12th Street North
Phase 2 will include Sioux Center's downtown as well as residential and commercial areas. Work is anticipated from 2024-25.

Designed for safety
Landscaped medians calm traffic and create a safe zone for pedestrians crossing the street. They also decrease the number of conflict points where traffic turns. Streetscape is being designed with a focus on visibility and safety.
Pedestrian routes and crossings
Rapid-flashing beacons are planned for many pedestrian crossings along Highway 75. Crossings will be painted, and some crossings are planned to have colored concrete in central Sioux Center. Sidewalks are part of the total design, running along the most of the 2.5-mile project.
Function for years to come
The City and project engineers developed a design based on safety and how the highway can best function and serve the community today and 40 years or more from today, the anticipated lifespan of the road design.
A Sioux Center Welcome
Highway 75 is our community's front door. Streetscape elements will create a welcome impression and a theme that carries through the community.
What does this project include?
The 2.5-mile Highway 75 reconstruction will be nearly end-to-end in Sioux Center. It involves replacing deteriorating pavement and rebuilding it in a safety-based four-lane design to serve the community for decades.
Why is Sioux Center replacing Highway 75?
The aging pavement and sub-layers of Highway 75 are deteriorating - some of it dates back to the 1930s. The City of Sioux Center wants to replace it in a design that focuses on safety, function and showcasing Sioux Center's character. The Iowa Department of Transportation has agreed to partner with the City on reconstructing this road and has committed more than $25 million toward this project. This partnership allows the City to have a say in how the replaced pavement will be designed.
How does the new design promote safety?
The new design includes median throughout the project. These medians limit left-turn conflict points where vehicles cross traffic, create a traffic-calming effect, and provide pedestrian safe havens at several crossings. Rapid-flashing beacons are planned for many pedestrian crossings. A new stoplight is planned for 20th Street South (near Pizza Hut).
Why does the design include medians?
Medians are designed to promote safety on this busy roadway. They limit conflict points from vehicles turning left and crossing traffic, create a traffic-calming effect, and provide pedestrian safe havens at several crossings. The design also includes several locations for vehicles to make a U-turn from a protected turn lane to visit locations on the other side of the roadway.
Where will there be sidewalks?
New and replaced sidewalks are planned for nearly the length of the project, starting at 20th Street South and stretching north to about 11th Street North.
Who is paying for this project?
This is a shared project between the City of Sioux Center and the Iowa Department of Transportation. For Phase 1, the Iowa DOT is paying about $9 million and the City is paying about $2 million. Phase 2 is set up to be an 85% DOT/15% City split for roadway construction, with the city covering utilities, lighting, and engineering costs and the DOT covering right-of-way costs.
