The Heart of Ohio Trail is currently opened in the Village of Centerburg. This trail, when completed, will offer 16 miles of walking, skating and biking trail. A horse trail will lie adjacent to the trail for three miles from Thayer Road to Tucker Road, which places the horse trail close to the Knox County Horse Park. The trail is maintained by the Heart of Ohio Trail group, a volunteer organization.

Good News! ODOT staff announced in September that the Knox County Commissioners will receive state funding in the amount of $1.7 million to construct a tunnel under US 36 east of Centerburg in 2008. Asphalt paving will also occur, from Bishop Road to Updike Road. Read a Mount Vernon News article concerning the grant.

The park district assists the trail organization and Knox County Commissioners (who own the land under trail) with landowner relations and trail planning.

For visitor safety reasons, bridges on the trail east of Centerburg to Mount Vernon are closed until bridge upgrades are made in early to mid 2008. The two bridges east of Thayer Road (closest to Mount Vernon) will remain closed until rehabilitation occurs in 2009 or 2010. Substantial progress has been made on development of the trail.
