Division 3.6 Tunnel closureX1

In the event of tunnel closure (long or short-term), users shall be informed of the best alternative itineraries, by means of easily accessible information systems.

Such alternative itineraries shall form part of systematic contingency plans. They should aim to maintain traffic flow as much as possible and minimise secondary safety effects on the surrounding areas.

Member States should make all reasonable efforts to avoid a situation in which a tunnel located on the territory of two Member States can not be used due to the consequences of bad weather conditions.
