More than 100,000 Welsh homes and businesses will gain access to super-fast broadband in 2014, in the next phase of the nation's fibre rollout.
The next 63 communities to receive an upgrade under the Superfast Cymru project have been revealed - with fibre services set to go live by the spring.
Locations in Abersoch, Bangor, Barmouth, Blaenau Ffestiniog, Caernarfon, Dolgellau, Harlech, Porthmadog, Pwllheli, Tredegar and Waunfawr will be among those to benefit.
The Superfast Cymru project - which is being jointly funded by BT and the Welsh government - has set a target of delivering 80Mb download speeds to 96 per cent of premises by mid-2016.
Some 57 towns and rural communities have either received an upgrade so far, or are scheduled to gain fibre broadband this year.
Liv Garfield, Chief Executive of Openreach, the firm responsible for managing BT's network infrastructure, noted that Wales in on "an exciting journey".
"We are making great progress with supercharging the country’s broadband speeds," she claimed.
"This project is already enabling businesses in rural as well as urban communities in Wales to grow and compete on a level playing field with competitors anywhere in the world and providing a myriad of opportunities for families to explore new horizons and applications that will enrich their lives."
Ms Garfield claimed that rolling fibre broadband out across Wales is "a complex project" that has required "meticulous planning and hard work".
"But we have been working closely with the Welsh government and our efforts are now really starting to pay off," she added.
Superfast Cymru will see around 3,000 new fibre broadband cabinets and 700km of fibre-optic cable deployed across Wales - enough to travel the perimeter of the country 330 times.
According to the project leaders, the rollout will help create up to 2,500 full-time jobs in the long-term, helping to boost the national economy.
