The City of Gahanna, in partnership with the Franklin County Engineer's Office, began planning this project back in 1996.  The project will help enhance roadway capacity with the widening of N Hamilton Rd between Carpenter Rd and US-62.  The roadway will be increased from its current status of one lane in each direction to two lanes in each direction with a center turn lane.  In addition, the project will reduce traffic congestion with the addition of two roundabouts at the Clark State Rd intersection and at the Northeast School.  To improve connectivity between the northern and southern portions of the city, a 10 foot wide multi-use path will be constructed on the west side of the roadway and a new sidewalk will be constructed on the east side of the roadway.

The construction on Hamilton Rd began on June 22, 2015.  The project will span three construction seasons, wrapping up in the Fall of 2017, weather permitting.  Work will include the relocation of utilities, installation of new water mains, installation of temporary pavement, relocating the traffic signal at Hamilton Rd and Clark State Rd, and the replacement of the bridge over Sycamore Run.  This work will carry over through this Winter and the Spring of 2016.  The remainder of the project will occur during the Summer of 2016 through the Fall of 2017.
