Sometimes you have to read the label, too. there's a mile stretch of dual

Interesting one near me.

That's unusual. I know stretches where the limit reduces to 30mph for
several hundred yards approaching a roundabout (not such a bad idea in
some circumstances) and, as a result, the opposite carriageway,
carrying traffic in the other direction, away from the roundabout, is
also restricted to 30mph (pointless, frustrating and inviting
infringement).
