It connects major road routes north of the river to those to the south. How the work was done The superstructure — the part of the bridge that sits on the foundations and carries the traffic - of the current bridge was designed as four, pre-cast box beams like a hollow box.
Part of London Bridge used to be a drawbridge. Civil engineer John Smeaton advised on the building of the bridge. Explore more civil engineering projects.

The People behind the bridge. Our people. Historic Bridge Lifts. Tower Bridge vs. London Bridge. Londoners will happily tell you which is which, but how do you tell the difference? Aren't they the same thing? Tower Bridge on Screen. Unfortunately, by the early 19th century the bridge was showing serious signs of wear and tear. Although the buildings that had once adorned its top had long been demolished, the crossing was still far too narrow and the arches that supported the bridge were a serious hindrance for ships passing underneath.
The circled area is the old pedestrian entrance which still remains to this day. It was therefore decided in that a new, larger bridge should be built in its stead. For the past 2, years, the position of the bridge has remained a nexus for economic development, although its physical construction has changed several times.
Timber bridges on the site were damaged by multiple fires and a storm. Mary Colechurch was completed in A. Henry II commissioned the first stone structure, also designed by Peter, on the site around years ago. Slightly to the west of the timber bridge location, it was a simple masonry arched bridge, like the Pont Neuf in Paris, and included a drawbridge.
For half a century the stone bridge was home to many buildings, including residences, shops and a chapel dedicated to St. Thomas of Canterbury. In fact, there were about buildings on the bridge, according to Green. With so much development, the bridge became constricted — not to mention the bathroom facilities dropped straight into the Thames — so the city started removing the buildings in the 18th century.
As the London Bridge continued to be a major transportation route even without its buildings, structural problems appeared. The arches deteriorated, and the bridge, which had experienced a variety of damage, was also slowly sinking. By the s, it was deemed structurally problematic, Green explains. Thus, a new bridge was proposed and completed in A masonry stone structure that was sturdier and highly engineered, it had been proposed by Scottish civil engineer John Rennie and constructed by his sons.
Situated upstream from the 12th-century bridge, which was quickly demolished, it lasted just years.
