Because the soil was too hard to bore through Because the tunnel was originally built between 1892 and 1897 where transport was primarily by horse, and horses do not like to be led down underground so when they used to see daylight at the end of the tunnel, they would typically bolt for the end, causing collisions with other riders. Therefore bends were added to the tunnel to avoid these situations. ............................................. Whilst the previous explanation sounds plausible, there is no mention of this in the 'design & construction' details. In 'British History Online', it says that "the proximity of the docks and the availability of suitable approaches dictated its slightly sinuous path".
