There's a short section of the A420 between Swindon and Shrivenham that becomes a single-lane dual carriageway, presumably to help traffic avoid hitting the central pier of the railway bridge under which it passes. There are 'keep left' signs either end but no "Dual carriageway ahead" signs. There is a 50 mph speed limit now but some time ago when I used to use it regularly it was NSL and at the time I always wondered if it was 70 mph for that stretch.
