A PLAQUE has been unveiled in Glasgow to honour a civil engineer who built three of the most famous bridges in the world.

Sir William Arrol was responsible for the Forth Rail Bridge, the Tay Rail Bridge and London's iconic Tower Bridge. He also built Great Western Bridge, over the River Kelvin, which is crossed by ten of thousands of motorists every year.

The Institution of Civil Engineers has now unveiled an iron plaque on the A-listed West End bridge to mark the 100th anniversary of the engineer's death.

The event was attended by William Campbell Arrol, a great grand-nephew of Sir William.
