|Route outline (key)|
The B3247 is a road in south Cornwall with four end points.
The main line of the B3247 leaves the A387 in Hessenford. It then follows the winding valley of the River Seaton to meet the sea at Seaton, a small resort with a shingle beach, from where it follows the coastline eastwards to Downderry. This section of road is largely S1 and appears to be no more than a local, residential street.
After Downderry the B3247 climbs away from the sea via a couple of hairpin bends (the view is excellent but the driver will have other things to think about). After the road has levelled out it widens to S2 once again shortly before reaching the unclassified road from Polbathic where it bends sharply right. The road narrows once more and it follows the coast as far as Crafthole. Here there is a most unexpected mini roundabout where a branch of the B3247 joins, having come from the A374 from near Sheviock. Until 1934 the road through Seaton was unclassified (though for a year between April 1934 and April 1935 it held the number B3272) and this branch was the mainline.
Continuing east the B3247 follows the coast to a fork by Tregantle Fort. At this point the second branch with the same number (formerly the B3248) goes to the A374 at Anthony.The mainline of the B3247 continues east along the Rame Peninsula, passing Millbrook. At Sollack Barn it turns north eastwards to pass Mount Edgcumbe Country Park before reaching its terminus at Cremyll. From there the Cremyll Ferry, for foot passengers only, makes its way to Plymouth. Indeed, the 1922 Road Lists claim that the B3247 started in Plymouth although this is as close as it has ever got.
