 Despite Somerton being situated in a rural area , the closest main road from Somerton is the A303 road that runs near the town and stretches all the way into northern Hampshire and finally ends at Basingstoke . The minor B3165 road runs through the town although the road is less commonly used and does not join to the A303 for another 4 miles ( 6 km ) . Two B roads , the <unk> and B3165 , run through Somerton ; the B3165 , mentioned earlier , starts in the town and runs southwards to the <unk> Langport road . The <unk> itself runs south @-@ east to the junction of the A303 and A37 roads at <unk> services .
