From Douai to Mortagne-du-Nord

Over 8 km, its course has been replaced by the Broad Section link. Once Douai has been passed, the river avoids the most industrialised centres and returns to a pleasantly rural character. It rejoins the Escaut at the Belgian border, but navigation is currently prohibited between PK 30 and 50 because the Lallaing drawbridge is dangerous.
