The completed project featured a wider roadway and drainage improvements on Route 73, Route 30, Berlin Cross Keys Road and Walker Avenue, with new ramps and access roads created to allow the retention of all of the traffic flows offered as part of the traffic circle. Crossings on Route 73 were combined into four intersections controlled by traffic signals. New sidewalks and curbs were also included, as were bike lanes. New basins, box culverts, pipes and inlets were added to improve holding capacity in storms and mitigate flooding at the intersection.
