Glass walkway on London Tower Bridge unveiled

Bird's eye view across the Thames – Visitors can watch pedestrian and traffic cross the River Thames from the high-level glass walkway. Each glass panel of the £1 million ($1.6 million) installation weighs more than 500 kilograms.

Rising roadways – Tower Bridge opens 1, 000 times every year for vessels, ships, sailing barges and cruises. During lift times visitors can watch the bascules raising below their feet.

Bustling bridge traffic – The new glass floor at the Tower Bridge spans 11 meters long between the north and south towers. London's red buses and black cabs can be seen from 42 meters above the River Thames.

Fashion concerns – Engineers had to consider the upward view for pedestrians below. Distance, angle and reflection during the day and deliberate lighting at night ensure there are no surprise views up skirts and dresses above.

Safe crossing – For those who might suffer heart palpitations, narrow wood panels along the side of the walkway offer respite from the view.

Old bridge, new attraction – London's Tower Bridge greets 600, 000 visitors a year. This year marks the 120th birthday of the bridge, which opened June 30, 1894. The eastern glass walkway will open December 1.
