The B3252 is a short link road in east Cornwall, which starts on the A38 east of Liskeard and runs towards Looe.
The road starts on the A38 near Trethawle, where a gap in the central reservation of the A38 provides access to/from the eastbound carriageway. It heads south via Horningtops to Byplane End where it meets the B3251.
Until 1935 the B3252 ended here and the B3251 took on the road ahead - but now it is the B3252 that continues on to end on the A387 at Widegates.
The B3252 is described in the 1922 Road Lists as Byelane End - Liskeard. However, its northern end has always been where it is now and the road has never reached Liskeard.
