dome, and installing new lighting. The work was needed because the dome, which last underwent repair and conservation in 1960, was rusting and some ironwork had fallen from the structure. Congress had appropriated no funds for the project, however. A $60-million, two-year restoration started in early 2014 included removing paint, priming and quickly repainting. Steel pins and "metal stitching" were used to repair cracks, and water damage inside was fixed. Scaffolding was erected around the dome in November 2014. The project was slated to be completed and the scaffolding removed in time for the 2017 presidential inauguration, and indeed all exterior scaffolding was removed by the end of summer 2016. Papers relating to the construction of the dome are archived at the Cornell University Library as Collection No. 3244.
