Can I just add a uneducated guess re the road to Warkworth.
If, when Amble was just a small settlement, could the road through not have been straighter, running from Marks Bridge, down Albert Street and across The High Street. That would take the road west of the Manor House, east of where the Gas Works grew up and re-join the road along the river roughly where the entry is for the marina. Other developments later could have necessitated the extension westward of High Street and the two right angle turns in the road as it now is.
Just a thought and no doubt historical facts will disprove my lay theory.
