Instortende brug onderstreept noodzaak onderhoud in USA

The bridge collapse on Interstate 5 north of Seattle this week highlighted the nation’s aging infrastructure and the lack of significant improvements in the six years since 13 people died when a Minnesota span fell.

Investigators haven’t determined what caused the failure of a section of the bridge over the Skagit River in Mount Vernon, Washington (BEESWA), after a truck struck some of its steel girders. The collapse followed the commitment of $48.1 billion in U.S. economic-stimulus funds for transportation projects since 2009.
