Here are the facts and figures that demonstrate the scale of the scheme.

1. The development will create a 5 mile dual carriageway

This will benefit the estimated 21,000 vehicles that use the A465 between Brynmawr and Gilwern.

Around 87% of the work is complete, including 2 new bridges at Glanbaiden roundabout and the concrete arch bridge at Gilwern – the largest of its type in the world.

2. The equivalent of more than 400 Olympic swimming pools worth of material has been excavated

This is more than 1.3million metres cubed.

The project includes fifteen bridges and 12,500 metres of retaining structures. The project is also using 16,400 metres cubed of reinforced concrete, 5,000 tonnes of reinforced steel, 109,000 tonnes of flexible pavement, and has installed more than 20 kilometres of pipework.

3. There are 750 tonnes of steel in the Jack Williams Gateway Bridge

The Jack Williams Gateway Bridge was named after a local World War One hero, following a public vote. The blacksmith from Nantyglo was awarded the Victoria Cross after single-handedly overpowering a German machine gun post in France and capturing 15 of the enemy. The bridge spans 118 metres and crosses one of South Wales’ most important environmental and ecologically sensitive areas.

4. More than 270 jobs have been created

The scope of the scheme, as well as its complexity, has brought a range of employment and training benefits to Wales and the local community.

More than 270 new jobs, 69 new apprenticeships and 120 work experience opportunities have been created. 300 school and college initiatives have been delivered, and 171 educational site visits have taken place.

The scheme has been designated National Skills Academy status by the Construction Industry Training Board, and received the Careers Wales Silver Award in 2019.

5. More than 30,000 trees have been planted

These trees within the scheme’s footprint help to reduce greenhouse gases and improve air quality.

Local nature has benefited from the Lapwing Mitigation project, which has seen three to four breeding pairs return to the site, and more than 6,850 tonnes of recycled glass has been imported from a local provider.
