This judicial investigation case revolves around a network of corruption and bribery between construction companies (MECO, H Solís, Montedes and others) and officials of the National Council of Roads (Conavi), the entity in charge of the development of highways in the country, which publishes the contracting posters and administers their tenders. President Alvarado ordered a full investigation of the Ministry and suspended all contracts with the involved companies.[78][79]
