I-35W Bridge Beginning to Age

Seven years after the Minneapolis I-35W bridge collapse occurred, the replacement bridge is starting to age. Bridge inspectors recently found cracks in concrete girders, a clogged drainage hole, and rust above the bridge’s piers. The new I-35W bridge over the Mississippi River was built in 2008 after the after the old bridge fell into the river on August 1, 2007. The collapse killed 13 people and injured 145. Improperly designed gusset plates were ultimately determined to be the reason for the collapse. Federal regulators also discovered that the gusset plates were not given proper attention during inspections.
