I'd just like to back up the above posters with regards to journey times, having lived in Doncaster most of my life and Bessacarr for the past five years, you can really trust me when I say that traffic is hellish during rush hour down Bawtry Road and around the Dome/Lakeside areas. It would easily take 40 minutes to do the journey. Having said that, for purposes of balance, Parrots Corner is quite a bottleneck so we'll have to see if adding an extra road into an already busy junction will help with the Bawtry Road traffic problems.
Still a small country lane to traverse for large lorries.
You obviously haven't been into the countryside much if you think Hurst Lane is a "small country lane"! Now it's not the M25 but it's certainly no narrower than the roads leading to LBA and EMA.
