This is probably my first ‘proper’ twilght session since November 2007.
The bridge is London Bridge in East London and I am facing the Financial District.
According to WikiPedia, there has always been a bridge at this site for the last 2,000 years and an earlier version of this bridge was the only bridge over the Thames in London until Westminster Bridge was opened in 1750.
The current London Bridge was designed by Mott, Hay and Anderson, constructed by contractors John Mowlem and Co from 1967 to 1972, and opened by Queen Elizabeth II on 17 March 1973.
It comprises three spans of prestressed concrete box girders, a total of 928 feet (283 m) long.
The bridge was built to be functional and long-lived, and, as such, it is noticeably less decorated than other Thames bridges.
