Safety Board Faults Construction, State Oversight in Fatal Colorado Accident
In response to the accident and its probe, the NTSB on May 31 voted unanimously to recommend new construction standards and better supervision by state highway departments, as well as consistent federal and state guidelines for design and certifying falsework for bridges and other highway structures.
The federal board investigates transportation accidents and recommends actions to improve safety, but has no regulatory authority. Although NTSB has investigated bridge collapses over the years, officials said the probe of the Colorado accident appears to be its first of an active highway construction site.
