Colombia’s Comptroller General’s Office is investigating the National Infrastructure Agency (ANI) regarding the rejection of a bid by Odinsa Vías for the "Conexión Centro" infrastructure project. The Comptroller has requested ANI provide justification for the rejection and address concerns regarding irregularities in toll rate differentials. The inquiry focuses on potential issues within the bidding process and pricing structures. Officials aim to determine if proper procedures were followed and if the decision was justified. This action signals heightened scrutiny of infrastructure project concessions in Colombia. Concerns about fairness and transparency in public works contracts are driving the investigation. The Comptroller’s findings could have significant implications for the future of the "Conexión Centro" project and related infrastructure development.
