The track for the 2016 Olympics in Engenhão has been laid out and will now be finalized ahead of a test event on May 14.
The stadium and track were scheduled to be completed in March but several setbacks and weather issues delayed the Mondo track's installment.
The track awaits the approval of the International Association of Athletics Federation, track and field's governing body.
The stadium is expected to hold 60,000 fans upon its completion.
Estádio Olímpico João Havelange was closed in March 2013 when officials noticed that the roof had a risk of collapsing.
Rio de Janeiro was awarded the Olympics in 2009 and will open the Summer Games with the opening ceremonies on Aug 5. Track and field will be contested at the stadium from Aug. 12 to 21.
