The meeting will be 4:30 p.m. Wednesday at the Pittsfield Township Hall at 6201 W. Michigan Ave.
Representatives from the Road Commission will be giving a short presentation on the scope of the project, including the plan for road closures and detour routes, and then will answer questions.
Construction of the $2.4 million, two-lane roundabout is slated to begin June 3. The roundabout will take the place of the traffic signal at the intersection.
About $470,000 of the project cost is attributed to the replacement of a 30-inch water main at the site.
The bulk of the project will be paid for with federal funds from a Congestion Mitigation and Air Quality grant and Surface Transportation Program-Urban dollars.
Costco, which built a store on Ellsworth that opened in June 2012, is contributing $500,000 to the project.
The remainder of the cost will be split between the city of Ann Arbor and the Road Commission, McCulloch said.
Additionally, Pittsfield Township will consider a resolution to invest $21,000 of its money in concrete work at the roundabout -- which the city of Ann Arbor may match.
The Road Commission awarded the contract for the project to the lowest bidder, Pamar Enterprises Inc., which is based in New Haven.
One lane of traffic in each direction on South State Street will be maintained during the construction in the project limits, which extend from just south of Interstate 94 to the Ann Arbor Airport.
However, sections of Ellsworth Road will be completely blocked during the project.
“There’s going to be delays,” said Mark McCulloch, project engineer for the Road Commission. “If you can avoid it, it would be in your best interest.”
Construction of the roundabout will be completed in five phases.
The first phase will begin June 3 and will consist of preliminary site work. McCulloch said it should last from one to two weeks.
Road closures will begin in the second phase in mid-June and should last to the middle or end of July, McCulloch said.

For drivers traveling on the east-west route, the posted detour route will be along Airport Boulevard.
Properties on Ellsworth west of State will still be accessible by way of Airport Boulevard or from the west side, McCulloch said.
The third phase will begin mid-August and last until the end of the month, McCulloch said.
During the third phase, Ellsworth Road to the east of State will be completely closed to through traffic. The posted detour route will be Research Park Drive.
The entire project will be completed by the middle to end of September, McCulloch said.
