The roads? Rights-of-way & property boundaries didn't get bombed, and one narrowing due to right-of-way passing through historical-significant properties restricts the maximum vehicle size for the entire road/region (https://goo.gl/maps/BzJrXer8HmF2)

Consider this local intersection ('junction'): https://goo.gl/maps/UPjtR5VdSXM2. It's a favourite for the practical driving test: from the left lane, turn right into the side street. It's extremely dangerous, as you have to creep around the corner to the left to get visibility of the oncoming 30mph traffic, without getting so far pass the side street's centre line than you can't safely turn in.
