01Background
Built before 2014, the Terre Rouge–Verdun road was struck in 2015 by a deep-seated landslide. A strategic link between the north and the centre of the country, it was partly closed to traffic.
02Objectives
To establish the causes of the failure, stabilise the ground for the long term and safely reopen the road to traffic.
03Results
In 2016 the Minister had the design and management failings of the original project formally established. The Road Development Authority called on the expertise of Cerema and IFSTTAR, French public agencies; from April 2018, 180 piles, each 26 metres long, were installed along five kilometres. The Minister visited the site on 2 February 2019, and the road reopened in July 2019.
04Impact
An essential link was restored to road users, and Franco-Mauritian technical cooperation in road geotechnics was strengthened.
