A474 Alltwen Hill Bridge Strengthening Work

05 May 2017

Neath Port Talbot Council is advising road users of essential strengthening work on the A474 Alltwen Hill Bridge in Pontardawe which will begin next week.

A four month programme of work on the bridge, which crosses the River Tawe at Pontardawe, will begin on Monday 8th May and is scheduled to finish in September.

The works will require the existing dual carriageway on the bridge to be reduced to one lane in each direction, with the exact layout depending on the progress of the works.

The works will include the replacement of the existing surfacing, joints, street lighting and waterproofing system on the bridge deck; refurbishing the bridge bearings and undertaking repairs to the abutments, piers and bridge deck.

The contractor, Ian Davies Plant Ltd will undertake a 5-day week programme, with the work taking place Monday to Friday between the hours of 7am and 6pm. Traffic management will be in place 24 hours a day for the duration of the programme.

No work will take place on Bank holidays without prior approval

The Alltwen Hill Bridge work is one of a number of projects under a £2.4M strengthening programme for bridges, which is part of a £59M programme of capital investment in the county borough for 2017/18.

The County Bridge strengthening programme also includes the recently completed works on Bont Fawr Aqueduct in Pontrhydyfen and planned works on the A474 river bridge which leads to and from Neath Town Centre. A further £1 million investment will be made to strengthen the A474 Vale of Neath Bridge between the A465 Saltings roundabout and the Neath Abbey Court Herbert roundabout.


Hasan I. Hasan, Engineering Manager said: “We would like to thank road users for their cooperation and understanding whilst this essential maintenance work is undertaken and apologise for any inconvenience caused.”
