Up to five hundred spectators will be accommodated in the free travel initiative. Interested cycling fans can go to www.gosmartdumfries.co.uk and book their place from Thursday 15th August.
The Council is working with community transport providers to ensure that people have the option of taking buses to the event from Dumfries, and direct from the Glenkens, Moffat, Upper Nithsdale and Thornhill.
The majority of buses will leave from DG One, Dumfries at 12pm, returning 45 minutes after the Scottish Stage finishes.
Councillor Finlay Carson, the Events Champion said, "The Tour of Britain is one of the most significant events to take place in our region each year and the Council is committed to creating access to it. Council funding of free buses to The Tour makes sense from an events management and environmental perspective.
"I hope that all 500 free places are taken up and that the thousands of spectators enjoy a fantastic day out at The Tour of Britain."
Stage One takes place on Sunday 15th September, with the race expected to finish between 15:15 and 16:15.
Please note, all spectator vehicles must have entered the Drumlanrig Castle Estate by 14:00 on the day of the stage. For further details please click here, where regular updates to spectator information will be provided ahead of Stage One.
