Congested roads aren’t just frustrating. They can be extremely dangerous. Now, imagine five busy roads converging at one intersection. This is the site where Grand Island, Nebraska, recorded 44 collisions in just three years.  

The city brought us in to find a solution to transform this hazardous intersection. Today, the improved intersection keeps people moving safely and efficiently.

“Roundabouts reduce severe crashes by requiring lower vehicle speeds and eliminating conflict points common in signalized intersections.”

After extensive research and an evaluation of the area, our team selected a five points roundabout design – a solution that is known for its proven safety and operational benefits. Our new design was selected to not only enhance safety, but to also reduce delays and improve traffic flow, says Project Manager Shane King.

“Roundabouts reduce severe crashes by requiring lower vehicle speeds and eliminating conflict points common in signalized intersections,” he said. “Roundabouts are widely recognized for offering improved safety compared to standard intersections controlled by stop signs or traffic signals.”

“What sets this roundabout apart is its complex design with five legs instead of the conventional four-leg roundabout.”

The new design replaced aging infrastructure with a concrete roundabout, upgraded drainage systems, relocated utilities, and added new signage and grading. We also were selected to lead construction management, while the project was underway. Despite the complexity – including carefully relocating a two-story home – the team completed construction ahead of schedule.

“What sets this roundabout apart is its complex design with five legs instead of the conventional four-leg roundabout,” Shane said. “It has helped improve safety, reduce congestion, and enhance traffic flow for motorists, cyclists, and pedestrians.”

The project even received the Project of the Year Award by the American Public Works Association, Nebraska chapter.

We also worked closely with the city to secure federal funding. Eighty percent of the project was funded by federal safety grants and 20 percent by local tax dollars. This funding strategy allowed the city to deliver a critical infrastructure upgrade at a significantly reduced local cost.

Public engagement was central to the project’s success. The team conducted multilingual outreach, stakeholder meetings, and 3D simulations to educate the community and gain support. Construction was strategically scheduled during the summer to minimize disruption to schools and businesses.

Since the five-points roundabout opened in 2023, Grand Island has reported a substantial decrease in traffic congestion, fewer delays, and enhanced safety for all users. The intersection now operates more efficiently, with smoother traffic flow and reduced vehicle idling, which means lower emissions and improved air quality.
