This category is for websites about the first bridge to cross the River Thames from The City of London to Southwark on the south bank.
This dates back to Roman times from AD43, though this category lists websites to the bridges called London Bridge, that replaced this on the same site between present day bridges upstream at Southwark, and down stream at the Tower of London;  Tower Bridge.
The present day London Bridge was opened to road traffic in 1974, after its predecessor from 1830 was dismantled to be rebuilt in Lake Havasu City, Arizona, which had in turn replaced a 600-year-old medieval multiple arch structure, including gateways and houses.
