Mr. Garang's political party says the body of the former rebel leader, who died Saturday evening in a helicopter crash, is lying at New Site in Southern Sudan.
Sudan's government on Monday declared a night curfew in the capital, Khartoum, to prevent riots that erupted following news of his death. At least 36 people were killed in the violence.
Mr. Garang was a key figure in the peace accord reached this year between the Sudanese government and southern rebels to end a 21-year civil war.
Sudanese President Omar el-Bashir and General Salva Kiir Mayardit, who was named by the SPLM to succeed Mr. Garang, have stressed that his death will not stop the peace movement.
