The A3121 is one of those curious upgraded routes created by Devon County Council in 1991. However, unlike its contemporaries – the A3079, A3122 and A3123 – the reasons for its upgrade are not easily explained.
Formerly part of the B3196 and B3210, the A3121 provides a link between the A38 Devon Expressway and the A379 coastal route from Kingsbridge to Plymouth. It effectively serves to provide a main road link from Exeter (via the A38) to a number of sizeable villages and suburbs to the east of Plymouth. In reality, however, much traffic uses various minor roads off the A38 further west towards Plymouth in order to benefit from using a greater proportion of that road's dual carriageway.
Wrangaton - Ermington
The A3121, along with the B3213, starts at a grade-separated junction with the A38 at Wrangaton, near South Brent. Only east-facing slip roads are provided, allowing exit for Plymouth-bound traffic and access for Exeter-bound traffic.
A left turn at the top of the exit slip takes you onto the A3121. The first section, for a mile or so to Kitterford Cross, is fairly narrow and twisty although two-lanes wide throughout. This part of the road was in fact originally the start of the B3196 to Kingsbridge, declassified in 1984 only to be reinstated south from Kitterford Cross to Loddiswell in 1997. Consequently, from 1984 to 1991 it was a spur of the B3210.
Kitterford Cross, now the A3121/B3196 junction, is a TOTSO for the A3121. The main line runs east/west from Avonwick to Sequer's Bridge on the former B3210. The road east to Avonwick and Totnes was downgraded in 1991 at the same time as the road west was upgraded. The B3210 is now extinct.
After Kitterford Cross the road runs through a valley for the rest of its journey to the A379. The small villages of Ugborough and Ermington are both located offset from the road on the north side, the only settlements of any significance on the route. Ermington is noteworthy for its church that has, for many hundreds of years, been adorned with a crooked spire. The village takes its name from the River Erme, which is crossed by the A3121 on the edge of the village.
Sequer's Bridge, where the A3121 gives way to the A379, is about a mile beyond Ermington and six miles from Wrangaton. From here the A379 runs west into Plymouth via Yealmpton and Plymstock, serving side roads to coastal villages Mothecombe, Newton Ferrers and Noss Mayo along the way. Eastbound via the A379 you can reach Modbury and Kingsbridge with access to more coastal villages including Bigbury-on-Sea.
