due to the fact that it did just that when people walked over it the first time & needed to be re-engineered so that it wouldn’t fall into the Thames! It was London’s version of “Galloping Gertie”- Tacoma’s own Narrow’s Bridge.

I enjoyed seeing the “Rubbish Eater” below the bridge in the Thames. It’s a novel idea whose time has come for the Puget Sound Region. Anyone have any ideas on how that could happen here in Seattle?
