The Welsh Government is investing £46M to boost the economy, including £2.7M for transport infrastructure.
The money will be used for investment in the Llangefni Link Road and the Northern Gateway Highway Infrastructure, which will open up the site to commercial development.
Most of the £46M will be used to support small business development and there will also be funds for aerospace training.
Finance and government business minister Jane Hutt said: “The need for targeted investment in infrastructure is well rehearsed and is central to the priorities set out in our Wales Infrastructure Investment Plan. Infrastructure investment is one of the main contributors to growth and jobs and has a positive impact on the economy.”
