The New London Bridge The modern London Bridge, constructed between 1968 and 1972, replaced Rennie's stone arches with prestressed concrete beams, measuring 104 meters (340 feet) in the middle span. The new bridge was designed by Sir Norman Foster of the architecture firm Rogers Stirk Harbour + Partners.
It is one of the most famous landmarks in London, and has become a symbol of London itself. The central section is made up of twenty-four large towers, each weighing nearly a million pounds, which support the deck above. The bridge connects Southwark with Borough, and is part of the A206 road. It has five traffic lanes, two bus lanes, and a separate bike lane.
After its initial success, the bridge became bankrupt and was acquired by the City of London Corporation who managed it until 1998 when responsibility was transferred to the newly created London Bridge Development Company. The company now operates the bridge under a contract from the city council.
The first bridge on this site was built in 1750 by John Rennie for the sum of £15,000 ($100,000 in today's money). It was a wooden structure that lasted only seven years before being destroyed by fire.
This was preceded by a series of timber bridges, the earliest of which was erected by London's Roman founders...

London Bridge has existed in some form or another for approximately 2,000 years. The London Bridge, which still remains today, was built in 1973. So, despite the fact that London Bridge has been here the longest, the actual bridge that stands today is one of London's more contemporary Thames bridges.
The first record of a bridge across the River Thames at this location dates back to 880 AD. Since then, there have been many changes made to the bridge by various architects and engineers including Thomas Paine who designed the current suspension bridge in 1829. In 1795, the previous bridge collapsed due to enemy action so it is likely that some type of structure has stood since 880 AD.
Today, the bridge carries traffic between South London and Kent. It is also popular with tourists who want to see a piece of London's history every time they go on vacation.
You may have seen photos of the bridge after it was destroyed by terrorists in 2015. Although it no longer stands, an image of the bridge before it was repaired following the attack can be found online.
After the attack, British authorities named the bridge as a possible target because of its popularity with tourists. However, experts believed that it would have taken significant resources to destroy and that there were better options for large-scale attacks.
Since the initial Roman crossing in AD50, London Bridge has seen several variations. To minimize traffic disturbance, the new bridge was to be erected 30 meters upstream of the existing crossing, enabling the medieval bridge to continue to function until the latter was completed in 1831. Its remains can still be seen today.
Tower Bridge originally had three towers: one at each end, and one in the middle. The central tower was 140 feet high and had four floors, while the others were only 70 feet high with two floors. It was this difference in height that caused problems for the designers who wanted to make the bridge look as elegant as possible. Because of this, they came up with a design where the central tower was made out of cast iron and the rest out of steel. The central tower was also given an extra floor above the others for better accommodation.
The first attempt to build the new bridge was made in 1824 but it collapsed after only three months due to serious design flaws. The second version was built following the original plans more accurately and opened for traffic in 1831. This is the version people know today with its three tall arches leading to the four-lane road deck and its two shorter outer spans leading to three-lane railway bridges.
The third version of the bridge was built between 1890 and 1893 with additional train tracks added underneath.
