You know, sometimes you're driving along, and suddenly you notice that the number of the road has changed. Usually this is because you have to "turn off to stay on" or TOTSO for short. Rarer, and more interesting, is where two roads end at the same place (or at least appear to).
Possible TOTSOs (ie, those which can be queried) are in italics.

A12:
-With A127, east of Romford
A13:

A33:
- Junction with A3024 in Southampton
A34:
- At junctions with A5079 and B5093 - two TOTSOs in southern Manchester right next to one another!
- West Midlands, Turns left in town centre when heading towards Walsall - straight on route is A4601. Caused by pedestrianisation of Cannock Town Centre
A35:
- With A350 in Poole, Dorset
A37:
- South of Farrington Gurney, Somerset - TOTSO with the A39
A38:
- In Gloucester town centre with A430
A40:
- With A418 between Milton Common and Wheatley. Debatable this as the A418 is signed to the M40 as a useless multiplex
A44:
- With A3400 east of Chipping Norton. The original start of the A44 - TOTSO caused by A34 renumbering after M40 completed. The status of this is disputable as although westbound traffic has the TOTSO signed, eastbound does not and runs on a short part of the former A361 and A34 instead
- With A429 in Moreton-in-Marsh (twice) Doglegs down the main street for 200 m
A48:
- With A48(M)
A52:
- Kingsley Moor with the A521, just North of Cheadle, Staffordshire
- With the A523 near Waterhouses heading from Ashbourne to Leek

A100 - A499[]
(wiki links need adding from here down to more road nos & Towns to link articles)
A104:
- First notable turn is right (albeit at a traffic light) from Essex Road into Balls Pond Road. Ahead would be the A105
- Next you have to turn left at the junction with Queensbridge Road. Ahead into Graham Road is the A1207
- Then it takes a twist at the A107 junction. If you are coming from Lea Bridge Road then ahead at the roundabout is an unclassified road, instead you should turn left and right further up

-At North Woolwich with A112 (signs say A1011)
A120:
-At Stanstead, M11 Junction 8
A124:
-At Beacontree Heath with A1112. A complex one. The junction was a roundabout till the early nineties. Now, heading north on the A124 Wood Lane you have to turn right to continue, or else you get on the A1112 Whalebone Lane. But the right turn is a short multiplex between the A1112 and A124 until you get to the roundabout where the A124 Rush Green Road diverges left and A1112 Rainham Road right! Heading west on the multiplex, A1112 traffic must turn right at the lights, and A124 traffic must turn left. Straight on westbound is the A1083 Green Lane
A181:
-At Gilesgate in Durham
A199:
-Westbound at Eastfield, on the Edinburgh/Musselburgh boundary. Left to stay on the A199, straight ahead for the B6415 (the old A199)

A422:
-With B4100 northwest of Banbury (caused by former A41 being renumbered post M40)
-With unclassified road west of Alcester (caused by A435 being realigned further east and renumbered A46)
A428:
-At Bretford
A429:
-West of Cirencester with the A433
