The B3440 is a short link road in east Devon.Originally unclassified, it became part of the B3391 in the mid-1930s. However, much of that road was downgraded in the 1990s but it seems the village of Uffculme was sufficiently important that it remained connected to the classified road network, with the B3440 doing the job.
The road starts at a roundabout on the B3181 on the northern edge of Willand and heads northeastwards. It is a fairly straight route across the fields and passes some houses and a few industrial buildings as it follows its course up the valley of the River Culm.
Presently we reach Uffculme and the road starts to wind a bit more. We follow Commercial Road, which is traffic-calmed, into the village centre. After passing through The Square the B3340 ends by the church when the road bends sharply right. The other roads here are unclassified but at one time the road ahead to Culmstock was the B3391.
