LONDON BRIDGE IS FALLING DOWN
On this day in 1831, New London Bridge was opened by King William IV.

Until the mid-eighteenth century the Old London Bridge was the only crossing on the Thames in London. It was damaged in a major fire in 1633, but in the fire of 1666 this damage acted as a fire break and prevented the flames from further damaging the bridge and crossing to the south side of the Thames. With its 19 narrow arches, it impeded river traffic and flow. Central piers were removed to create a wider navigational span. Widening and the removal of its houses was completed in 1763, but it remained relatively narrow and needed continual and expensive repairs. In the early nineteenth century it was decided to replace the bridge with a new construction. New London Bridge was opened in 1831 and survived until it was replaced in 1972. At that time, the 1831 bridge was dismantled and reconstructed in Lake Havasu City, Arizona. Wikipedia
