On the third day of the assembly of the main construction crane, three courageous Skanska employees walked out along the horizontal segment of the crane to attach cables and to untie guidelines. After assembling the main crane the support crane was taken down and away. Broadway was closed for the entire day as well as Prescott Street all two blocks of it. These images captured on Monday November 21, 2011.
