Inspections found that the surface was too soft on the Twin Sails Bridge Link Road which was built by main contractor Blackwell under a £2m deal.

Local council inspectors found issues with the binder material used in the road surface.

In places the binder had not fully hardened allowing the main road stone material to be pushed down as traffic passes over it.

Work is ongoing this week to remove and replace sections of the road surface that have been affected by the problem with the binder.

Julian McLaughlin, Head of Transportation Services, Borough of Poole, said: “Earlier in the year the binder material, which forms part of the road surface, was found to be defective.

“Remedial work was undertaken but it has now become evident that these measures have not been successful.

“The link road plays an important role in improving traffic flow and easing congestion in the town so it is essential that these remedial works are undertaken as soon as possible.

“The contract under which the Link Road was constructed makes provision for a 12 month defects period.

“Therefore any remedial work required during this period, including these repairs to the road surface, is the responsibility of the contractor so there is no cost to the local taxpayer.”
