1910. Queensborough Bridge
[The sailboat and steamer are reminders that 1910 looked a lot different than today. Judging from the low skyline in the background, I assume this was taken from the Manhattan side.]
Significance:  At the time of construction [1901-1909], the Queensboro Bridge contained the longest cantilever span in America. (And it "was designed for heavier loads than any other bridges." [NYCDOT] "With a total length of 7,449 feet [including approaches], at the time of its completion it was the fourth longest bridge in the world." [study])
Specifications:  Cantilever Bridge; steel construction; channel spans of 1,182 feet and 942 feet, two anchor spans of 630 feet, shore arms of 469 and 459 feet; cantilever trusses 60 feet apart.

[It appears that reconstruction work has been ongoing since 1978. It seems the major work was done in the 1990s. The current contract (6) consists of misc. work.]
