Check out the Ohio rail trails page, bring up the map and click on the Columbus area. It shows that columbus has several trails that run through the area. I don't live there but my brother does and we rode together down the Olentangy trail we started as far north as it goes and rode south through OSU campus into downtown. It was a really nice trail and seems to give access to neighborhoods along the way. It looked to me like Columbus is trying to build a network of rail trails that will help to make cycling in the area easier.
