Ohio State Route 529

The route heads southeast through the city and Marion Township passing through residential neighborhoods.

At the intersection of Marion Cardington Road and Richland Road, the state route turns towards the east and passes under the US 23 freeway without an interchange.

After this point, the route's surroundings become more rural as travels southeast towards Cardington.

After entering Morrow County, the route continues through rural farmlands before entering the village limits of Cardington on West Williams Street.

The state route continues south until it reaches Nichols Street; here it turns left and eventually becomes Chesterville Avenue and exits the village.
