|Route outline (key)|
Thanks to some diligent research at the National Archives, it would appear that the route of the A4016 in Bath was along St. James Parade, Monmouth Street and Monmouth Place. This was, of course, before the A4 was extended from Bath to Bristol; the same documentation notes the A4 as terminating at the junction of George Street and Milsom Street, with the road ahead being the A431. In order to keep to the strict 1922 rules about roads being in zone, this would have put the zone boundary running down Milsom Street, Stall Street and Southgate (the northern end of the A367) to the River Avon, and leaving the A4016 correctly in zone.
After the bombings in Bath during the war, much of the route of the former A4016 has been redeveloped, so the A367 now runs further south along the river and through Green Park, meaning that the central section of the A4016 is now unclassified, and one-way, allowing traffic out of town but not back in.
