Christ the Protector in the southern city of Encantado will be 43m (140 ft) high with its pedestal, making it the world's third tallest Jesus statue.
A head and outstretched arms were added to the structure last week, which was begun in 2019.
The idea came from local politician Adroaldo Conzatti, who died in March with Covid-19.
The $350,000 (£255,000) project is expected to be completed later in the year, the Association of the Friends of Christ group which is organising it says.
