The original 1940 mile-long suspension bridge, third longest suspension bridge in the world, collapsed in a windstorm four months after it was completed, earning it the name, “Galloping Gertie.” A replacement bridge was completed in 1950. Currently, a new bridge is being built parallel to the existing 1950 bridge to expand traffic capacity. The 1950 bridge will accommodate traffic traveling westbound while the new bridge will carry eastbound traffic.
