COLUMBUS (June 7,2010)A week before the Ohio Department of Transportation (ODOT) begins improvements on a major gateway in Central Ohio, drivers on State Route 315 will see dozens of signs urging them to have a game plan they know before they go.

Signs notifying motorists  are now located at ten entrance and exit ramps that will close along the three-mile corridor from I-670 to the North Broadway exit.  Ten entrance and exit ramps will remain open when construction begins June 14.

This year, crews will make improvements to the roadway surface of SR 315 south and eight bridges.

Both directions of traffic will use SR 315 north, which was improved last year when  construction began on phase one of the project.

ODOT is investing a total of $24 million dollars to improve SR 315 and several bridges from I-670 to the North Broadway exit.

ODOT expects all lanes of traffic on SR 315 south including all entrance and exit ramps to be open by September 1. Last year, the improvements to SR 315 north were completed on budget and ten days earlier than estimated.

Along with a Web site,, ODOT has also set up a phone line that provides 24-hour information on the construction project. The telephone number is (740) 833-8268. The Web site,, features a map to assist drivers through the construction zone. Along with directions to more than a dozen destinations along the gateway, the map also offers drivers alternate routes other than SR 315.

ODOT continues to work with the Ohio State University and many businesses along SR 315 to assist customers, clients, patients, and visitors to the area during construction.

ODOT also reminds drivers to Slow for the Cone Zone. Area law enforcement will enforce the 45-mile-per-hour speed limit through the three mile construction zone. Reduced speed signs will be posted every half mile on SR 315 in both directions.
