Repairs to the road surface outside Swansea's new high-profile car park will not be carried out for months, it emerged today. Holes appeared in the surface at the entrance of the new Oystermouth Road car park just months after it was laid.

Original roadworks caused weeks of tailbacks in the summer as the access to the National Waterfront Museum car park alongside the leisure centre was completed.

Thousands of visitors to £30.8 million museum will eventually use the car park every year but Swansea Council says road users will be facing a bumpy ride at least until the end of March.

A spokeswoman for Swansea Council said: "The resurfacing works on Oystermouth Road were undertaken by the developer's contractor as part of the works for the Maritime Museum.

"The developer is responsible under a Highway Agreement to carry out the works to a defined specification."

The council said it has carried out some emergency work already but the full repair will not be carried out for months.

"The resurfacing works undertaken are not satisfactory and the developer has been advised of this," said the spokeswoman. "The council has carried out some urgent repairs in the last few weeks to ensure public safety is not put at risk. It is anticipated that the road will again be resurfaced prior to the end of March. The delay in this work being carried out is weather related and the work will be carried out during the night."

The Swansea group of the Institute of Advanced Motorists said the delay is unacceptable. Group member Derek Evans said: "It's a pity that it has got to go on so long and whenever they do the work it will cause a lot of inconvenience.

"Obviously if there was an ideal time to do the work it would have been during the winter months when traffic levels are lower because of fewer tourists being about."
