Stands A, B, and C span a combined length of 400 metres and have a total capacity of 5,260 people.
The work has been completed after around two weeks of preparations.
Workers are installing the floor for the stage and stands.
The stands have wave-shaped canopies and dedicated zones for media, medical support and other facilities.
The military parade will take place along Le Duan Boulevard in District 1 in front of the Independence Palace.
The parade area will be equipped with LED technology, virtual reality and other advanced technologies to showcase footage and display visual graphics.
As many as 20 LED screens have also been installed along major inner-city streets so residents and visitors can watch the celebration live.
Since April 15, barriers have been erected along the section of Le Duan Street where the stands are located to restrict vehicles. Post-celebration dismantling and ground restoration are slated to be finished on May 1-12.
