B3182 (defunct?)	A30 Heavitree Road inExeter	A377 in Friars Green, Exeter	Became a portion of the B3183 in 1935, despite that route being shorter. The route may have returned to the B3182 designation, according to Devon County Council and some maps, although it is unknown why this short link needs a specific number. First used between Countess Wear and Sandy Park when the previously downgraded A378 was upgraded back to Class II status between 1935 and 1948. This B3182 is now unclassified as traffic takes the A379 spur to the M5 instead. Next used between Exeter and Countess Weir along a former portion of the A377 (was the A377 before the M5 was built); this was upgraded again in the 1990s to a portion of the A3015.

Originally ran from Newton Abbot to Shaldon. Declassified after the 1980s probably due to downgrading of the A379 at its eastern end (although this has been reversed)
B3196	A3121at Kitterford Cross,Ugborough	A381at Sorley Cross, Sorley, south ofLoddiswell	ThroughLoddiswell.A road of the same number briefly connected two parts of the original route of the A380 inNewton Abbotto enable traffic to avoid the railway station.

B3208	A323 Ash Road, Aldershot	A31 near Farnham	Formerly part of the A324 before the A331 was built. Originally connected Halwell to the B3207. Became a spur of the A3122 sometime after the 1970s, although signage on the ground has traffic routed away from the road.
B3209 (defunct)	A379 west of Churchstow	B3197 southwest of West Alvington	Renumbered to a branch of the B3197, and was upgraded to Class I status in the 1970s, but then returned to the B3197 for reasons unknown. Now part of the A381.
			Possible number for the apparently downgraded A3209. The A road lists mention the number, but the B road lists do not. There is also no other evidence that the route was ever downgraded, and is still shown on maps and signs as A3209.
B3210 (defunct)	A379 near Flete	A381 near Totnes	Originally ended at the A385 at Avonwick, but when the A385 was rerouted along the former B3372 in the 1950s, it was extended along the old A385 to the A381. In 1991, the portion from Flete to just past Ugborough was upgraded to the A3121 and the remainder declassified.
B3211 (defunct)	B3210 atErmington, Devon	A38 atIvybridge	Declassified in 1984.
B3212	B3181 at Whipton	A386atYelverton	East-West road acrossDartmoor
B3213	A38/A3121atWrangaton	A38atIvybridge	Runs almost parallel to theA38,thoughIvybridge. Originally a short loop off the B3212 near Dunsford. The western part became part of an extended B3193 by 1928, and this also took over the remaining eastern section in 1935, though as a spur of the B3193. The western section was declassified in 1991.
B3214	A374east ofLaira	B3238 / B3250 in Mutley	Originally ran from the A396 south of Tiverton to the A377 on the eastern side of Crediton. Renumbered as an extension of the A3072 in the 1960s.

B3219 (defunct)	A386 near Folly Gate	A30 in Sourton Down	Okehampton western bypass; renumbered as a portion of the A386 in the 1960s.
	B3320 near Winkleigh	A30 (nowA382) at Whiddon Down, nearOkehampton	Created 1991, became a portion of the A3124 in 1997.

B3228	A31/A325 at Moor Park, Farnham	A31/A325 at Cox Bridge, Farnham	Was the A31 (later A325) before the southern bypass opened. While the A325 signs have been removed, the new number has not yet been posted. Originally ran from the A373 (later A361, now bypassed) in South Molton to the A377; renumbered as a southern extension of the B3226 in 1935. Number also appeared on maps along a road in Dartford, but this is a typo for the B2228.

B3234	A39atBarbrook,Lynton	A39at Lynmouth Hill,Lynton	Originally ran from Bideford to Appledore; much of route became part of the A386 by 1927 and the remainder renumbered to B3236, although the A386 was later extended over this section as well. A 1953 map (showing the now-built A386) labels the section along Northam Road as the B3234, suggesting the road got its number back when bypassed. This is likely a mistake as other maps show it as unclassified and the B3234 was already in use elsewhere by then.
B3235 (defunct)	B3234 (now A386) north of the Long Bridge,Bideford	A39 at The Quay, Bideford	Declassified when the A39 bridge was built and reassigned to a bypassed section of the A386. Most maps show the route as part of the A386, and Devon County Council has no record of it. The route was signed as B3235 however. Signage changes in 2011 now indicate that the route is part of the A386.
B3236	A386 at Northam	A39Bideford Bypass,Northam	Loop fromA39along Atlantic Way,Westward Ho!Originally began at Appledore, but this section is now part of the A386, which also took over the B3236 in Northam town centre. The road originally continued to the A39 at Abbotsham, but this was declassified when the parallel A39 Bideford bypass was built.

B3248	A39west ofClovelly	Hartland	Links the village of Hartland with the A39. It is split into two parts, one running east from Hartland and a separate section running south, thus the road meets the A39 at two separate points. Originally ran on the Rame Peninsula, from the A389 (now A374) in Antony to the B3247 near Tregantle Fort; renumbered as a spur of the B3247 in 1935.
