Re-imagine a new Great Plain Avenue rotary in Wellesley. 

Reconstruction on the Wellesley Avenue at Great Plain Avenue rotary reconstruction project began in late July 2020. Work on the roadway also includes the Rice Street intersection to Brook Street intersection, and Brook Street to the Fuller Brook Road intersection. The project is expected to be completed in January 2021.

A number of proposed improvements are included in the project which will realign Wellesley Avenue, Seaver Street and the Great Plain Avenue rotary.

Granite curbing will be installed, along with hot mix asphalt sidewalks, cement concrete wheelchair ramps to meet current ADA standards, modifications to the roadway drainage system, cross walks, and new signs. The roadway improvements also include pavement milling and overlay, new pavement markings, bicycle lanes, and a street lights within the rotary area.  

A new sidewalk will be installed along Great Plain Avenue and Brook Street.

The work is being accomplished by J.H. Lynch & Sons, Inc. and their subcontractors, under the direction of the Town of Wellesley Department of Public Works.   

The work will take place Monday through Friday between the hours of 7:00 AM and 5:00 PM. Police details will be onsite during the project to minimize impacts to traffic and other roadway functions. Two lane traffic will be maintained throughout the majority of the project, although, there may be lane shifts to provide ample construction area for the contractor to perform the work. Drivers should use alternative routes during the construction hours.
