A programme, first broadcast in October and November 1968 on 4ZA Invercargill, about the history and building of the Homer Tunnel.
It includes interviews with people who knew William H. Homer, the pioneer who discovered gave his name to the Homer Saddle and had the idea for the tunnel.
The work went on from the 1930s throughout the Depression - some of the workers were college graduates who were happy to have any job available.
Interviews with men who worked on the tunnel - they describe the hard work, the camps they lived in and food they ate. They talk about disasters such as avalanches and coping with the isolation.
It was an expensive and ambitious project and the tunnel was finally opened to the public in 1953.
