Brazil's navy said on Friday that the body was found 3.7 miles from the Juscelino Kubitschek de Oliveira Bridge. Another eight people remain unaccounted for.
Several cars and trucks plunged into the Tocantins River after a section of the bridge crumbled on Sunday, AP reported.
Police operating on the border of the northern states of Maranhao and Tocantins said four trucks, two cars, and two motorcycles entered the river.
The 1,748-foot-long bridge between the cities of Estreito and Aguiarnopolis was built in the 1960s. It is about 800 miles north of the capital, Brasilia.
