Concept of street projectWe'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.
