It has a centre span measuring ft, and two ft side spans. With only three spans, London Bridge also now has even fewer piers, which created improved, wider navigation channels for river traffic.
The headroom under the bridge was also increased by 2ft 3in. The design, as I have already observed, was made by my father, but no detailed working drawings, specification, or estimate had been prepared by him; it fell to my lot, therefore, to do this. As the first bridge, and first road bridge, in London, the historic significance of London Bridge is clear. It provided the first-ever permanent crossing of the River Thames for early people, horse and wheeled traffic, and now for vehicles, too.
Before the bridge, people had to rely on ferries to cross the river. It was such a well-used bridge that it led to Southwark Bridge being built to try to relieve the congestion. In engineering terms, it demonstrates the progress in materials used in bridge building — from the early timber to the now much stronger and longer-lasting concrete and steel.
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. There was a strict requirement for the bridge to remain open as much as possible during its rebuilding.
The traffic congestion and limited working space at the bridge meant that the precast box parts were brought up the river by barge from the casting yard in Surrey Commercial Dock. A temporary gantry a bridge-like overhead structure with a platform to support equipment such as a crane , built across the river on column supports, was used to put the precast box units in place.
The gantry was able to carry one box of the new bridge at a time and move it sideways into position. The box units were then connected with joints made of concrete. There once stood a chapel dedicated to Thomas Beckett on London Bridge. Many fires damaged London Bridge, even in its stone construction, including the Great Fire of London in The heads of beheaded traitors used to be mounted on spikes and displayed on the bridge.
The granite face work and parapets of the old bridge were sold to McCulloch Properties, Inc, of California, and was rebuilt on a new bridge structure at Lake Havasu City, Arizona.
This damaged the ship as well as the bridge. The job you end up with in civil engineering is likely to link back to what you studied at school, college or university. Here you can see your options at any age. London Bridge Year: Area improved The bridge helps connect major road routes north of the Thames to ones south of the river. Solved the problem Enabled people to cross the River Thames.
Used engineering skill Built a concrete and steel bridge. London Bridge, courtesy of burge Provide the first crossing of the River Thames in London. A second timber structure built in its place was destroyed in a fire. In , a priest and engineer, Peter de Colechurch, replaced it with a stronger stone bridge. Many shops and houses were built along the rest of the bridge. Sir John Rennie about his father, also Sir John Rennie, who died before his designs for the 19th century bridge were put into action.
Difference the bridge has made As the first bridge, and first road bridge, in London, the historic significance of London Bridge is clear. 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.
