ST. PETERSBURG — The twin golden spires of the Sunshine Skyway bridge meet at the entrance of Tampa Bay, forming our most iconic symbol. It also marks our greatest tragedy. It was 39 years ago that the storm-blinded freighter Summit Venture crashed into the support columns of the old Sunshine Skyway bridge, causing a 1,200-foot span of the bridge to collapse into the bay. At 7:33 a.m., 35 lives were lost. They died in the six cars, truck and Greyhound bus that fell 150 feet into the water below. The bus took 26 lives. Nine people died in the other vehicles.
