A bypass on one of Wales' key road links through Pembrokeshire was officially opened by Deputy First Minister Ieuan Wyn Jones on Wednesday.

As one major road improvement opens, Mr. Jones also confirmed that this important project is to be extended to Llanddewi Velfrey, allowing further improvements for the region.

The Minister unveiled a plaque to mark the recent completion of the A40 Penblewin to Slebech Park Improvement scheme, near Narberth - in a ceremony attended by a children's choir drawn from two local primary schools, Narberth Community Primary School and St. Aidans Voluntary Aided School, Wiston.

Mr. Jones also announced the second part to this scheme, between Penblewin to Llanddewi Velfrey. The project will provide better overtaking opportunities to improve journey time reliability and road safety.

Mr. Jones said he was delighted to welcome this scheme, which will improve safety and journey time reliability along the A40 - one of the primary road links between mainland Europe and Ireland.

In a statement, he said: "There's been talk of improving this particular stretch for decades - as far back as 1990 the old Welsh Office commissioned consultants to investigate the options.

"Completion of this scheme marks a further improvement of our transport infrastructure, in line with the One Wales programme of government - and it liberates the centre of Robeston Wathen from the effects of heavy trunk road traffic, improving safety and quality of life for the local community.

"Despite the pressures on our budget, we want to press ahead with vital investments like this as fast as possible. That is why I am also delighted to be able to announce today the extension of this scheme between Penblewin to Llanddewi Velfrey. This will further improve this important road."

The Penblewin to Slebech Park Improvement scheme that was opened provides improved overtaking opportunities using a '2+1' road layout which will improve journey time reliability and road safety - the first time for this design to be introduced in Wales.

The design and construction work, undertaken by the Costain team, using the early contractor involvement form of contract, has delivered the scheme on time and to budget, using sustainable construction and good practice to ensure minimal environmental impact.

Mr. Jones said that he was pleased that excellent communication had been maintained with the local community throughout the construction phase.

The operation of an 'open door' policy and effective public liaison has been recognised by a number of awards, including an Award for 'Project of the Year 2010' by the Association for Project Safety.

'Investment welcomed'

Clr. Jamie Adams, Pembrokeshire County Council's cabinet member for highways and planning, said: "Improving the transport infrastructure of Pembrokeshire has consistently been an objective of this authority, and we welcome the Welsh Assembly Government's investment into the A40, improving road safety and journey times. We also acknowledge the tremendous environmental benefit that has been achieved for residents for Robeston Wathen."
