Yesterday saw the most spectacular part of refurbishment works end with a 100-meter long truss installed atop the Marseille stadium. Opening is planned for this summer.

Though less impressive than in early renderings, this roof is still one of the most unique structures in the world. Yesterday the last 200-ton piece of steel trussing was placed over Tribune Jean Bouin, the completely rebuilt main grandstand. The span of Bouin's roof is at 100 meters, a remarkable size.

This phase marked the very last works during Vélodrome's redevelopment. All of the concrete and steel superstructures are ready, though the cover still needs to gain its final strenght before temporary supports can be removed.

With major works delivered and no delays in past two years, the stadium is safe to be delivered in June and reopened in August, when Ligue 1 starts the 2014/15 season.

There were also no construction cost overruns and the budget of around €270 million ($370m) remains to date. It's expected to be recovered within 35 years by the stadium's new operator, Arema.
