Reports indicate that three companies have taken the opportunity to buy the bidding rules for the Colombian La Linea traffic tunnel. Conconcreto, Ferrovial and Cóndor are said to have purchased the rules that are a prerequisite for entering the bid contest. Representatives of the client, the Colombian national highways institute, have recently been canvassing contractors to promote the 8.6km tunnel after several previous setbacks relating to project finance. The contract could be awarded in early May.
