Film produced by Optimum Productions 1964 - 65
The Channel Tunnel was one of the largest engineering projects undertaken in the 20th century. It forms the vital link between the transportations systems of the UK and continental Europe.
This film begins by looking at the early surveys of the channel sea bed in the 19th century but then focuses on the detailed study in 1964 -65.
Halcrow, and especially the "father of modern tunnelling" Sir Alan Muir Wood, were involved with this site investigation and design elements of the project.
