"I'm surprised all the major London bridges aren't under one authority."The London County Council was responsible for Hammersmith Bridge, and the responsibility was passed on to the Greater London Council in 1965.Then guess what? "The Local Government Act 1985 dealt with the abolition of the GLC, and transferred non-trunk road bridges in their entirety to one of the two London boroughs that each bridge lay within – the choice of borough to be decided between the two councils, or failing agreement, by the Secretary of State for Transport. In addition to the bridge, the London borough taking responsibility also gains 100 yards of approach road from the other borough. For Hammersmith Bridge, the London Borough of Hammersmith and Fulham took responsibility." (Wikipedia)So, thanks to Thatcher and the Tories, "Hammersmith & Fulham (H&F) Council is the highway authority for Hammersmith Bridge and is responsible for its maintenance and repair."
