A court of arbitration, part of the Czech Chamber of Commerce, has ordered the building firm Metrostav to complete Prague’s Blanka tunnel complex within five months. The court also said the city of Prague had to pay 4.04 billion crowns to the firm. The decision came months after work on the controversial tunnel was halted last December over disputes between the company and Prague City Hall. A Metrostav spokesman said the firm would resume work as soon as it received the payment while Prague Mayor Tomáš Hudeček said the city would pay the required sum. However, the construction company has in the meantime demanded the city pay another billion crowns; the court of arbitration will deal with the latest petition in June. The Blanka tunnel, designed to channel traffic from the city centre, has been criticized as an overpriced and non-transparent project. Its total costs are expected to reach some 36 billion crowns.
