Excerpt from the April 4, 1964, issue of Science News Letter
When and if engineers build the long-planned tunnel connecting France with Britain under the English Channel, the new U.S. Chesapeake Bay Bridge-Tunnel, about to carry traffic, will receive some of the credit for making it possible. England sent two engineers to work on the mammoth bridge-tunnel, which has been called one of the five future wonders of the world…. The recent agreement between British and French Governments to build the Channel tunnel calls for twin 32-mile-long tubes in which electric trains will speed back and forth…. The ventilation problem of exhaust fumes in such a long tunnel would be too difficult to permit auto traffic.
