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.

Demcy : high impact operation on the sun highway !

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.
