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.  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.  The remainder of the project will occur during the Fall of 2016 and continue through the Spring/Summer of 2017.

In anticipation of the two roundabouts on Hamilton Road that are planned to be functioning at the end of November, the City has prepared short instructional videos demonstrating how to safely navigate through these roundabouts.  Click the image below to watch these instructional videos.

Status (as of November 2016)
  • Crews are working quickly to complete base paving operations and curb installations for the roundabout islands this Fall on Hamilton Rd and if weather permits, the goal is to complete all curb and base paving operations on Hamilton Rd, and have the roadway and both roundabouts functioning by November 30, 2016.

On the Horizon
  • As the project continues to move forward towards completion, there will be some changes to the maintenance of traffic over the next few weeks, which will include lane shifts and the installation of temporary pavement markings throughout the project.  These changes affect both the north bound and south bound lanes of Hamilton Rd as well as Clark State Rd.  Motorists should expect delays and impacts during their commutes at the intersection of Clark State Rd and Hamilton Rd as construction crews work to complete the roundabout and splitter islands in this area over the next couple of weeks.
  • Looking to construct the relocation of Carpenter Rd in the next several weeks, which may result in a closure for several days on Carpenter Rd.  Information will be updated via our website and social media.

Project Timelines
  • Project is still continuing to progress ahead of schedule. As time and weather allows this Fall and as we move into Winter, the contractor will continue to work to complete remaining concrete work for driveways and sidewalk, while all final restoration and surface asphalt will be completed in the Spring/Summer of 2017.
