THE A338 Spur Road is such a busy route that any incident – no matter how small – is likely to cause traffic jams.

So the inspection work being carried out on the major road’s safety barrier yesterday was always going to cause large tailbacks. Dorset highways bosses were facing a no-win situation.

Although the necessary work was advertised in advance, there are inevitably going to be motorists that don’t see it.

The answer in the future may be improved signage on the day and along the route beforehand.
