The annual maintenance works scheduled for 22 September to 24 October on the Aisne a la Marne, from Conde sur Marne to lock 13 at Sillery have been cancelled, due to lack of funds. That means there will be no closure of the Aisne a la Marne this fall. I believe the scheduled closures in that time period on the Marne will still go ahead.
