There's a series of plaques at the midway point, depicting the history of its construction. My favorite shows an interesting event which occurred just after the first cables were strung across between the two towers:
"In 1876, at nearly 60 years old, Master Mechanic E.F. Farrington was the first to ride a cable the length of the bridge, to the uproarious cheers of thousands of spectators."
Somebody mentioned the view of the Empire State Building; her's an interesting view, including sort of a "cross-section" of Manhattan, from the FDR on the East river to the top of the ESB.
Looking up at one of the towers:
Another virew: much of the steel has been replaced, but it all still retains the original design.
A bonus: Bell JetRanger making its way to the heliport near Wall Street.
Next: a walk around the Battery
