Useful in both directions between Menetou-Ratel and Verdigny, this connection connects the 39 to the 23 and 30 – from Vailly and Jars you can reach Verdigny more quickly; conversely, starting from Verdigny you will pass above Sens-Beaujeu to reach Boucard then the Beaujeu woods and its 24/25 routes, before going up via the 39 towards the Château de la Verrerie.
