An event marking 40 years of the Orwell Bridge is being run throughout November.
The photographic exhibition - featuring many images that have never been seen by the public before - is being held at the Suffolk Food Hall.
December 17 will officially mark the 40th anniversary of the Orwell Bridge opening.
The exhibition is free and open to all, every day, in the Cook House restaurant at the Suffolk Food Hall, running until the end of November.
Photos from Howard Morris and Paul Templeton have been collated - while the exhibition also includes a unique social history video made by Matt Marvel of BBC Suffolk, recording the lives of those involved in the build.
Some of the images were featured in the Platinum Years exhibition at the Suffolk Show this year, while many have never been on display to the public before.
The chronological display documents from when the construction started in October 1979, featuring photos by electricians and others who worked on the build.
When it opened, at 190m the main arch was the longest pre-stressed concrete span in the UK – making it effectively the widest non-suspension bridge ever made.
Director of Suffolk Food Hall, Oliver Paul, said: “The fact that the Orwell Bridge was voted this year, by EADT readers, as the third most important icon in the county, is evidence of its importance and symbolism.
"We’re proud to live in its shadow, and we enjoy its majesty, particularly as the light changes on it every day and through the seasons.
"It’s a privilege to host this exhibition, giving the public a chance to see the scenes behind a staggering construction.”
