Georgia Has Bridge Accidents Waiting to Happen
The collapse of an I-5 bridge into the Skagit River in Washington reminds us, again, that our bridges are literally falling down around us. There are an estimated 66,000 structurally deficient across the country. In Georgia, there are 941, which ironically is quite good, placing the state 42nd in total number of structurally deficient bridges. But the news is not quite grounds for celebrating. There are three bridges in Georgia like the I-5 bridge that collapsed. They are functionally obsolete and fracture critical. This means they are well beyond their design thresholds for the number of vehicles they carry and the weight of those loads. This increases the risk of car accidents, which as the I-5 Bridge demonstrated, can bring the structure crashing down. The problem is many of these bridges were built as inexpensively as possible. They have no structural redundancies, so if a single girder or truss fails,…
