BACKGROUND:
City Council awarded Contract 17-085 to TranSystems Corporation in April 2017 for an amount not to exceed $1,342,673.23.

Improvements along North Aurora Road include widening the existing three lane road to five lanes and installing a multi-use trail, sidewalks, streetlights, storm sewers and noise walls. The Naperville Township Road District shares jurisdiction of this section of North Aurora Road and is participating in the project per terms of an intergovernmental agreement. A federal grant for $6,000,000 was also secured for the project.
Change Order #1, in the amount of $38,275, was approved by City Council in August 2018. This change order was processed to design a noise wall adjacent to residential properties and add an additional intersection design study.
