Frome is a medium-sized town in north eastern Somerset. Historically, it was the largest settlement in the county, its prosperity fuelled by a series of mills along the riverside. Some of these survive, but only one or two still house factories, the rest having been converted into flats or demolished.
Today the town has a bustling centre, bypassed by the main A361 to the east. Its old route is now the B3090, which meets the A362 at a junction where the B3092 also departs to the south. To the east of the town, the former B3098 is now the A3098 as far as Westbury.
Before Frome's Bypass was built, the A361 used to pass straight through the middle of the town, along what is now the B3090. The other roads within the town are still much as they were 50 years ago, but to the east the B3098 has been reclassified as the A3098 as far as Westbury. It is not clear what number the un-numbered B road shown on the map to the left had.
