Too-heavy truck 'apparent' cause of deadly French bridge collapse A truck weighing over twice the maximum limit probably caused the deadly collapse of a bridge across a river in southwest France, the prosecutor leading the investigation said Tuesday. The bridge detached from suspension cables on Monday and plunged into the river Tarn, causing the deaths of the truck driver and a 15-year-old girl.\\nThe truck weighed more than 50 tonnes, over double the bridge's weight limit of 19 tonnes, prosecutor Dominique Alzeari told a press conference. \\n IMAGES AND SOUNDBITES
