The Danube will remain blocked by bombed Yugoslav bridges through the winter, with the cost of removal estimated at as much as $31.5 million, the Danube Commission announced, adding that private shippers are racking up losses far in excess of these figures. "Environmental damage of considerable consequence goes far beyond what it would cost the international community to clear the bridges and re-establish navigation," Hellmuth Strasser, head of the commission's secretariat, said. He added that re-establishing the river's shipping is the most difficult task the Danube Commission has faced since World War II. Experts estimate it will cost between $15.8 and $31.5 million to remove bridges bombed by NATO during its air campaign against Yugoslavia, Strasser said.
