A 30-foot-tall sign collapsed onto the eastbound travel lanes of Interstate 66 on Saturday, striking a pick-up truck.
The truck’s driver survived without serious injuries and the Virginia Department of Transportation launched an investigation. Bridge engineers were assessing the accident near Monument Avenue in Fairfax on Sunday.
“This is a very serious matter and I want to assure motorists and the public that VDOT will get to the bottom of what caused the collapse so we can prevent this from happening again,” VDOT Commissioner Greg Whirley said.
The fallen sign was last inspected in December 2007. Officials said the investigation is expected to last several weeks, and could not say whether a fast-moving snow squall passing through the area contributed to the collapse.
