In south London, England, a road bridge over a railway line collapses and kills six workers.
On the southern outscirts of London, a new stretch of track on the Mitcham and Sutton line through a cutting on Mitcham Common had required the construction of a brick road bridge spanning it. Cracks in the structure of the almost completed bridge had appeared and on this day it collapsed as workers were attempting to repair it. Six men were killed when buried under a hundred ton of bricks. (By John Osborne)
