Work's beginning today on the controversial Canford Bottom junction improvements...

Preliminary work on the busy roundabout for the A31 between Wimborne and Ferndown is due to get underway, with the main work starting next month - all to be completed in time for the sailing events in Dorset at the 2012 Olympics.

There are fears the junction won't be able to handle the excess traffic from London, and that motorists will feel the impact of the work from next month.
