Manoa Roundabout Debate: Residents Voice Concerns Over Safety and Space (2026)

A heated debate has emerged in the Manoa community, centered around a proposed roundabout at a five-way intersection. This proposal, put forth by the Manoa Neighborhood Board, has sparked controversy and divided opinions among residents.

The roundabout debate: A battle for safety and efficiency

The idea of installing a roundabout at the intersection of Manoa Road, Oʻahu Avenue, and Lowry Avenue was introduced by Vice Chair Christopher Moylan, who cited research supporting the benefits of roundabouts. Moylan argued that roundabouts can reduce traffic backups and improve flow, especially in areas with multiple lanes.

However, many residents strongly opposed the proposal, raising concerns about the size of the intersection and the potential impact on traffic. They questioned the need for such a change, especially given the lack of reported accidents in the area.

"I've lived here for over 55 years, and I've never witnessed any accidents at this intersection," shared a longtime resident. "If it's not broken, why fix it?"

But here's where it gets controversial...

Supporters of the roundabout argue that it could alleviate traffic congestion, especially during peak hours. Benjamin Gerwig, a Manoa Valley resident, believes a roundabout would be a welcome solution. "During school drop-off times, the traffic backs up significantly. A roundabout could definitely help manage the flow," he said.

Another resident, Scott Yamashita, agreed but emphasized the need for driver education. "A roundabout could work, but only if people understand how to use it. I've seen confusion at other roundabouts in Hawaii, so education is key," he added.

The Department of Transportation Services (DTS) acknowledged the community's discussions and stated that they regularly evaluate various traffic control options across Oahu. They highlighted the effectiveness of roundabouts in certain locations but noted that each intersection presents unique challenges.

"The existing configuration and limited right-of-way at this particular intersection would make a raised roundabout challenging to implement. It could require acquiring property from nearby homes, adding complexity and cost," the DTS explained.

The department assured the community that they will continue collaborating to find solutions that prioritize safety, mobility, and neighborhood considerations.

And this is the part most people miss...

The roundabout debate in Manoa highlights the delicate balance between improving traffic flow and preserving the character of a neighborhood. It's a complex issue that requires careful consideration and community engagement.

So, what do you think? Is a roundabout the solution, or are there better alternatives? We'd love to hear your thoughts in the comments below! Let's spark a constructive discussion and find a way forward that benefits everyone.
