Sorry its been too wet to go out and take photos.

An example where the road become too narrow for lane markings as it
crosses a bridge, the lines recommence on the other side when the road
becomes wide enough.

Again lines end where the road becomes too narrow, cars can pass but you
have to wait for anything much larger.

Maybe this one is silly, http://g.co/maps/atszn
The road is a lot less than 3m wide, the lines indicate a warning for
the give way as it reaches the trunk road ahead. It is still a single
lane.
