Bundybear - Unfortunately, until the new link is built from M18 jnc 3, it is a bit of a long way around. From the A1 southbound, you can either come off at jncs 38, 37 or 36 (they're all about the same timewise) and go through Doncaster, or come off at jnc 34 (Blythe) and effectively double-back on yourself via Bawtry.
