An engineering company in Gloucestershire is building 10 new bridges to help restore infrastructure damaged by floods in Pakistan.
A shipment of the 98ft (30m) structures, made by Lydney-based Mabey Bridge, are to sail from London to the Khyber Pakhtunkhwa district this month.
They are expected to arrive in the region by the end of September.
The United Nations said more than 17 million people have been affected by the disaster.
A Mabey Bridge spokesman said the firm had received an urgent order of 500 tonnes of steel bridges last week.
He added that once the bridges arrive, they can be assembled easily using unskilled labour.
The shipment is part of £64m government aid for the country.
International development secretary Andrew Mitchell said: "Everything has been destroyed in the pathway of these floods, roads and bridges."
