315 Ramp Closures begin June 25, 2017 to complete ramps that will eliminate weaving. The close is temporary through August.

The I-270/US 23/SR 315 interchange has been identified as the third most congested interchange in Central Ohio. The completion of this project is vital to the City of Worthington, as it will bring much-needed improvements designed to decrease congestion and improve traffic flow and safety of the interchange and surrounding roadways. It will also greatly improve access to the City through its northern gateway for businesses, residents and visitors to our community. Visit the Ohio Department of Transportation (ODOT) 270-23 website to see “live” traffic cameras, get project updates and sign-up to receive traffic alerts.

The 23-270 portion of the project is nearing completion, view the latest update from the ODOT North Side Fix page.

315 Interchange Underway


Construction on the final phase of the North Side Fix, at I-270 and SR-315 is underway. As part of the project, the Olentangy Trail is closed north of Worthington. Please see the project information from the Ohio Department of Transportation, including an alternate route for the bike path. The bike path is expected to reopen by the end of November 2016.

New ramp for U.S. 23 south to SR 315
ODOT will build a new ramp from U.S. 23 south to SR 315. This will be separate from the U.S. 23 south to I-270 west ramp. ODOT will also build two bridges for traffic coming from U.S. 23 north and south going to I-270 west that will go over the ramp to SR 315.

New Lane for I-270 East to U.S. 23


ODOT will build an additional lane on I-270 east that starts just west of Linworth Rd. This new lane will be a bridge over top of the SR 315 ramp and will be the designated exit lane for I-270 east traffic to access U.S. 23.

New Ramp from SR 315 south to I-270 east and U.S. 23
ODOT will eliminate the "loop ramp" from SR 315 south to I-270 east and build a new "flyover ramp." There will also be a new bridge built for SR 315 north traffic that wants to go to I-270 east and U.S. 23. The new ramp from SR 315 north and south will be two lanes – one for traffic exiting at U.S. 23 and one for traffic staying on I-270 east. The combination of these new travel lanes means there will be less weaving and merging or "jockeying" for the same piece of pavement.

Reconstruct part of the Olentangy Trail


About 1,000 feet of the Olentangy Trail will be reconstructed underneath the new interstate ramps at I-270 and SR 315. It is not safe for cyclists and pedestrians to use the trail during heavy highway construction. That's because heavy equipment will be stored on the trail to allow crews to build the bridge and piers that support the new ramp. For more information view the Olentangy Trail Alternate Route (PDF).

I-270 and US 23 Reconfiguration

Reconfigure two of the ramps at the interchange of I-270 and US 23


Two of the “loop ramps,” the ramp from I-270 E to US 23 N and the ramp from I270 W to US 23 S, have been reconfigured. ODOT added traffic signals at each of the new ramps to allow for better flow of traffic.
