* 271, 272, 273 do NOT serve Batheaston - they go around the bypass
Interesting that you picked that particular example out...
Those who may be planning a bus trip between Melksham and Batheaston (or vice versa) in the near future need not despair, though. Faresaver X72 runs hourly during Monday-Saturday daytime, and serves Batheaston itself, rather than going round the bypass.
