The city of Ames will be working on Duff Avenue, from Seventh Street to 13th Street starting Tuesday.

The Duff Avenue project will consist of sanitary sewer repair, curb and gutter replacement, reconstruction of the Ninth Street intersection, sidewalk ramp replacement and milling and overlay with new asphalt on the existing driving lanes.

The project is scheduled to be constructed in three phases. The first phase will close the inside lanes of traffic for the sanitary sewer work.

The second phase will divert traffic to two-way on the existing southbound lanes to accommodate the curb replacements, half of the Ninth Street intersection, and the milling and overlay of the existing northbound lanes.

The final phase will divert traffic to two-way on the existing northbound lanes to accommodate the curb replacements, the other half of the Ninth Street intersection, and the milling and overlay of the existing southbound lanes.

The entire project should be completed the week of Oct. 26 or earlier. Traffic will be maintained at all times through the project including access to area businesses and Mary Greeley Medical Center.

Vehicle access in or out of residential properties along Duff Avenue will not be allowed in order to maintain a safe traffic flow.
