GIS - 2 February 2015: Emergency preliminary works will be carried out on the Terre Rouge-Verdun Link Road (M3), along the Valton-Ripailles corridor so as to stabilise the embankment of the road. The works will be effected under the supervision of an expert team from the Japanese International Cooperation Agency (JICA) as well as ARQ Consulting Engineers, a South African organisation.
This was announced during a press conference by the Minister of Public Infrastructure and Land Transport, Mr Nandcoomar Bodha, on 30 January in Port Louis.
Several remedial measures will be taken in the future to stabilise that road and ensure that it becomes a reliable road on a long-term period, said the Minister. In fact, a new design for the failed part of the road will be produced, and it is expected that the road will be constructed on ‘pilotis’. The emergency works would consist of the construction of a drain system and horizontal drains to take out the water, decreasing the water table, and stabilising the embankment, the Minister pointed out.
Also, appropriate arrangements would be made to avoid traffic congestion along the Port Louis-Sottise Dual Carriageway (M2) during peak hours, added the Minister.
It is recalled that, an investigation was carried out by the experts of the JICA, following information received from the Police on 18 January 2015 regarding the cracks that had been identified on the Terre Rouge - Verdun (M3) Highway at about one kilometre from Valton roundabout.
The main cause of the cracks and settlements were identified as accumulation of excessive water following heavy rainfall. The geotechnical experts from JICA, along with the Engineers of the Road Development Authority, have, after conducting appropriate tests, proposed remedial measures, including the complete closure of the road, covering of the cracks to avoid further infiltration of water, and construction of drains on the mountain side as well as on the valley side.
The Terre Rouge - Verdun Link Road was financed by the Agence Française de Développement under a € 40 million concessional loan granted to Mauritius. This road, bypassing the town of Port-Louis, was constructed to help ease traffic burden in the city-centre.
