Demcy : high impact operation on the sun highway !

In the Drôme region, our teams demolished the old A7 motorway bridge at Bourg-lès-Valence. For three days, from Friday 10 to Monday 13 June, 50 employees were mobilized to dismantle the bridge over the RN7.

In total, the 3,000 cubic meters of concrete of the prestressed structure were demolished. The demolition materials will be crushed, de-merged and then crushed on site to be reused as fill. 

This was a large-scale operation that mobilized a large number of machines: 10 demolition excavators weighing from 30 to 60 tons, with their equipment (about 30 tools including concrete shears, iron shears, crushers, rock breakers, etc.), 3 A35 dumpers, a wheel loader and a bulldozer. Once the structure has been demolished, the earthworks carried out by Forézienne immediately followed, and a new phase of work began: the construction of the new motorway bridge by Eiffage Génie Civil. 

Congratulations to all our mobilized teams and thank you VINCI Autoroutes for their confidence.
