Rockfalls on the RD 1091 in La Grave caused the closure of the road and therefore the Grenoble-Briançon link.
”A retaining wall upstream of the road, a second downstream, as well as a protective net were swept away with the fall of this rock mass,” explains Jean-Marie Bernard, President of the Department.
You must go through La Mure, Corps, Gap and Embrun via the RN 85 and the RN 94 or postpone your trip.
A temporary system should be put in place this evening
RD 1091 / La Grave: closure of the road following the fall of a rock weighing more than 30 tonnes
Weather conditions continue to make headlines and impact high-Alpine roads and structures. This Tuesday morning, the fall of a block weighing more than 30 tonnes led to the closure of the RD 1091 (Briançon-Grenoble route). The event occurred during the night. ”A retaining wall upstream of the road, a second downstream, as well as a protective net were swept away with the fall of this rock mass,” explains Jean-Marie Bernard, President of the Department. ”A geotechnical investigation took place this morning using a drone,” continues Marcel Cannat, Vice-President in charge of roads. ”The most urgent thing today is to purge the elements
unstable of the wall which overhangs the road. A specialized company will arrive this afternoon to begin this work. Then we can consider a temporary device
to restore traffic, while the damage to the retaining walls and protective equipment is repaired, in particular.” ”The RD 1091 is a very important axis for the Hautes-Alpes. An axis which links large population areas and between two Regions. It is therefore a very busy route and we
We can’t skimp on safety,” adds Marcel Cannat. ”The weather conditions for the next few days are not forecast to be good. A significant rainy event is still forecast this Thursday. The conduct of the work will also depend a lot on the conditions that the technicians will encounter in the coming days.” For the moment, the RD 1091 is closed to traffic below La Grave in the direction of Grenoble, approximately 1 km before the limit departmental with Isère.
