Roundabout at Eagle and Amity intersection complete; dedication to be held Friday morning

Meridian – From a four-way stop to a circle – the Eagle and Amity intersection has taken on a new shape that now has motorists driving through the recently constructed one-lane roundabout.

Earlier this week the intersection was re-opened to traffic after a three week closure which allowed the project to be completed more than one month ahead of schedule. Final work at the intersection is wrapping up and the new roundabout will be dedicated at a brief event on Friday morning (September 21) at 10:30 on the southeast corner.

"While other roundabouts exist in Ada County, this is the first at a major crossing of two busy roads. It will be a learning curve for some motorists, but the new intersection will keep traffic moving safely now, and for years to come, at a lower cost," said ACHD Commission President Rebecca Arnold.

During its busiest hour of the day, approximately 1,100 vehicles use the intersection. That number will someday increase and necessitate expansion of the roundabout to two lanes. Growth in the area will drive a future expansion to two lanes when the volume doubles.

About Roundabouts 


Roundabouts keep traffic moving efficiently and increase safety. They reduce the number of accidents by more than 48 percent compared to signalized intersections, primarily by lowering the potential points of conflict.

How to use a roundabout:

  • Slow down
  • Yield to other vehicles or bikes in the roundabout
  • Proceed counter-clockwise
  • Drivers already in the roundabout have the right-of-way
  • If an emergency vehicle approaches, immediately exit the roundabout and pull over; do not stop in the roundabout.

Nampa Paving began construction of the $700,000 roundabout at Eagle and Amity in early August.
