The sifting of more than 800 cubic yards of debris recovered from ground zero and underneath roads around the lower Manhattan site began in April and ended Friday.
The greatest number of remains -- 37 -- were found from material underneath West Street, a highway on the west side of ground zero. The new debris was uncovered as construction work made new parts of the site accessible.
The city began a renewed search for human remains in 2006. More than 1,800 remains have been found.
Some have been matched to previously unidentified Sept. 11 victims.
