Remove extra boundary way and fix turn restrictions

Detach boundary way from highway

Separate highway from boundary

Beloeil electoral district boundary should reuse municipality boundary way

These three islands I just added are not appearing above the water and I'm not sure why. They have natural=coastline in the right direction and role inner on the Baie de Rupert relation, just like Gushue Island farther north.

Name "D'Auria Street" added to relation/2389633 in changeset/133341895. Probably a mistake.

This island and many others are in both the Akwesasne and Dundee/Le Haut-Saint-Laurent relations. I was unable to determine which relation they should belong to. The whole area needs boundary cleanup.

Many of the parishes in New Brunswick along the border with Quebec have separate boundary ways. These should use the same ways as the provincial boundaries when possible.
