The Iowa Department of Transportation will proceed with design and construction of a reduced conflict intersection (RCI) at U.S. 63 and Black Hawk County Road C‑57 north of Waterloo, Iowa, after completing a feasibility study and deciding the change will improve safety at the location. Work is scheduled to begin in spring 2028, with design work starting immediately.
What a reduced conflict intersection means
RCIs are traffic configurations intended to lower the number of potential collision points between vehicles, an approach that transportation engineers in North America have increasingly adopted where turning movements at high‑speed intersections create a risk of serious crashes. The Iowa Department of Transportation said studies show these intersections can improve safety and reduce serious crashes.
"Based on the results, staff will move forward with plans to design and build a reduced conflict intersection..."
The DOT made the decision to move ahead after reviewing the feasibility study and receiving concerns from road users about the intersection. Officials said funding is available for the project, allowing the agency to advance design quickly and begin construction in the spring of 2028.
Process and oversight
The DOT indicated design work will start immediately and that the agency will continue to monitor the intersection after the RCI is built to ensure it operates safely. The announcement included a point of contact at the DOT’s District 2 office for questions about the project.
- Location: U.S. 63 and Black Hawk County Road C‑57, north of Waterloo, Iowa
- Action: Design to begin immediately; construction planned for spring 2028
- Purpose: Reduce number of vehicle conflict points; improve safety and reduce serious crashes
Local and regional context
Although this project is in Waterloo, Iowa, its announcement echoes conversations in Ontario and across Canada about measures municipalities and provinces can take to reduce intersection fatalities and serious injury collisions. Reduced conflict intersections are one of several engineering countermeasures—along with roundabouts, median barriers and signal timing changes—that transportation planners evaluate when responding to collision clusters or public concern.
In Ontario, municipal and provincial engineers have sometimes looked to U.S. examples when assessing new intersection designs. The Iowa DOT’s decision to move quickly because funding is available underscores how budget and timing shape whether and when safety infrastructure is delivered. For communities watching similar problem intersections, the path from feasibility study to design and construction offers a roadmap for advocacy, technical study and procurement.
Details and follow‑up
The Iowa DOT has published further material about RCIs and posted an image of the planned intersection layout on its website. The agency named a field services coordinator in District 2 as the contact for inquiries. Officials said the DOT will continue to monitor the intersection after construction to confirm that it is operating as intended.

For Waterloo, Ont. readers, the item is notable as a cross‑border example of how transportation agencies respond to safety concerns at rural and suburban intersections. It also illustrates how funding availability accelerates project timelines. Municipal and provincial officials, as well as community groups focused on road safety, often track such examples when considering recommendations for local road networks.
