Ann Arbor OKs State/Ellsworth Roundabout
At its May 7, 2012 meeting, the Ann Arbor city council authorized an agreement between the city of Ann Arbor and the Washtenaw County road commission for a $2.520 million roundabout project at State and Ellsworth.
The current design calls for a roundabout that is 150 feet in diameter. All four approaches to the roundabout have two lanes entering and two lanes exiting, except for the northern approach from South State, which will include a third lane. The planned design features include non-motorized paths that connect with the existing sidewalk system and new on-road bike lanes.
