Oklahoma City has opened its first-ever double roundabout — a traffic layout locally dubbed the “Peanut” — at a recently reconfigured intersection, marking a visible shift in the city’s approach to managing congestion and improving safety. The new arrangement is already drawing attention from drivers, planners and neighborhood residents as officials begin to monitor how it performs in daily traffic.
Photos circulating online show the pair of circular junctions fitted with fresh pavement markings, directional signage and raised central islands that create the peanut-like shape. Municipal crews finished the final touches this week and reopened the corridor to regular traffic.
What a double roundabout is and why it matters
A double roundabout consists of two closely spaced, single-lane circles that handle turning movements separately instead of one large rotary or traditional signals. That separation can reduce conflict points where vehicles cross paths and can slow turning speeds, which are linked to fewer severe collisions.

For commuters and local residents, the expected benefits are straightforward: smoother vehicle circulation, shorter idling times at intersections, and potentially safer crossings for pedestrians and bicyclists. City traffic engineers say they chose this configuration to address recurring backups at the site while keeping long-term maintenance costs manageable.
- Nickname: Locals call the layout the “Peanut” because the twin circles resemble the shape.
- Design elements: Two adjacent roundabouts with central islands, splitter islands to guide traffic, and new crosswalks.
- Intended benefits: Reduced speeds through the junction, fewer vehicle conflict points, and improved continuous flow.
- Implementation: Roadway markings, updated signage, and adjustments to curb lines completed by municipal crews.
Early reactions and what drivers should know
Initial photos and videos posted by motorists show drivers proceeding cautiously as they learn the new pattern. Transportation officials urge motorists to reduce speed, yield at entries, and follow the posted arrows until they are comfortable with the layout.
Pedestrians and cyclists should also note that crossing locations have been reoriented; users are advised to use the designated crosswalks and follow new signal prompts where provided. The city plans to place temporary signs and message boards while the public adjusts.
How the project performs will be measured in the coming months. Traffic counts, travel-time studies and crash data will help determine whether the double roundabout meets goals for traffic flow and safety, and whether similar designs will be pursued elsewhere in the region.
For now, the “Peanut” is open to the public and visible in recent snapshots taken from the site — a small but tangible experiment in urban traffic design that could influence intersection choices across Oklahoma City. Officials say they will provide updates as monitoring data becomes available and any fine-tuning is completed.
