Port bosses in Lynn have outlined their plans to improve the site, which they say will secure its future for several decades to come.
The port’s operator, Associated British Ports (ABP), is spending £3.3 million on a new bulk storage unit and a state of the art crane, that will enable cargo to be processed more efficiently.
The unit is the first new storage facility to be built on the site since 2000.
ABP chief executive James Cooper said: “It’s an investment for the next 30 years.”
Political and business leaders were given a tour of the site on Friday to see the work for themselves.
North West Norfolk MP Sir Henry Bellingham said: “We have a thriving port and it’s going from strength to strength.”
Work has already begun on a new £2.1 million bulk store, covering around 3,400 square metres, which is expected to be completed by the summer.
The ceremony saw the formal unveiling of a new crane, worth more than £1 million, which will allow staff to process cargo loads on larger ships more efficiently.
ABP is also planning to build new timber storage sheds, which will enable its timber and agriculture goods operations to be conducted in completely separate areas of the complex.
The port already handles around half a million tonnes of goods each year.
Mr Cooper said: “I’m really thrilled to see the level of investment that’s going in here.
“This is very much led by the local management and their judgement about the opportunities that exist and is a big vote of confidence in the future of the port.”
Sir Henry added: “What it reveals is, if you invest in new equipment, you will get new customers.
“We have a port that is growing. We have a team at the top of ABP which is committed to King’s Lynn and that is really exciting.”
The project is part of a £1 billion investment programme by ABP in its 21 sites across Britain.
