A picture of gol sur - tribuna. They've managed to close that big area in a matter of weeks. The stadium's accessibility from this side shouldn't be a problem in 2-3 months. The huge staircase is also nearly finished that fans will need to use from now on. Most of the tribuna side is also accessible.
The parking lateral - gol norte is the least advanced part of the stadium. As you can see, they still didn't finish even the foundation, although further up they finished the access level already. The reason they work in parts here is, because they only recently removed an earthen ramp for vehicles. They also started with the second ring here, but it plays no role if the stadium is ready to play football in obviously. The imprortant parts are the accessibility and the work inside, so people are safe enough to attend the games.
But these pictures also show how huge the stadium will actually be if you consider the gigantic underground floors you won't see when all is finished. Without a doubt it'll be the biggest stadium in Europe, not only in seat capacity, but also in square meters.
