Clyde Tunnel marks 50th anniversary

Glasgow's Clyde Tunnel has marked its 50th anniversary.

The crossing beneath the River Clyde was officially opened by the Queen in 1963.

The Princess Royal will attend a ceremony to mark its half century, and will meet some of the workers who dug the tunnel by hand.
