A465 Aberdulais Roundabout East and West Overbridge- Essential Bridge Deck Refurbishment Works

Share

Where and Why?

Starting 23/05/2021, the essential bridge deck refurbishment works will be undertaken on the A465 Aberdulais roundabout.

Built in 1975, the 65 metre long Aberdulais Overbidge spans the A465 and the Tennant canal. The bridge is 46 years old and is in need of repair. During a recent inspection, a structural defect was identified in the columns supporting the bridge deck. A lane closure and temporary propping system were put in place initially but now a permanent repair is to be undertaken.

The first phase of works will include critical concrete repairs to this column. Followed by further bridge deck refurbishment and waterproofing works under full closures during the school summer holidays.

Diversions and Safety Measures

The works will require a series of total and lane closures of the gyratory carriageway between the A465 eastbound onslip and exit to Tonna/Neath (A465). Traffic will be diverted east on the A465 to Resolven and back to Aberdulais on the A465.
