Thirty years ago, on 17 December 1982, Suffolk's Orwell Bridge bridge opened as part of the A45 (now A14) to carry traffic over the River Orwell on the outskirts of Ipswich. Construction work began in October 1979.
Ipswich-based photographer Charles Whitfield King documented the bridge's construction. The £24m bridge was built from a pair of concrete box-girders. Its main span is 190m (623ft). At its peak, more than 300 people were employed in the building project alongside a team of Dutch engineers.
The design of the bridge, engineered by Sir William Halcrow and partners, took into consideration the impact on the Orwell Estuary and the needs of the Port of Ipswich. More than 19,000 tonnes of steel was used in the build.
It took three years to complete construction work. Piles were sunk 40m (131ft) in to the river bed to support the two concrete box sections that hold up the centre span.
The west bank of the River Orwell was the main site of activity during the production of the bridge and was home to the site offices. The San Antonious ferry was used to take supplies between the two banks. The Cliff Quay Power Station closed in 1985 and was demolished in November 1994.
Thousands of people took the opportunity to walk the 1,287m (4,222ft) span of the Orwell Bridge between Wherstead to the site of the former Ipswich Airport when it was opened by David Howell, the Transport Secretary at the time, in December 1982.
