CLEVELAND - The Ohio Department of Transportation has launched a probe into why highway signs above the Interstate 480 Valley View Bridge crashed onto vehicles during a strong thunderstorm.
Three highway signs weighing between 300 and 500 pounds blew off their mounting Tuesday shortly after 4 p.m. during during rush hour traffic.
The occupant of one vehicle, Gregory Badger, remains in critical condition at MetroHealth Medical Center.
Another motorist said the winds were so strong it "picked up his car" off the road.
A Five On Your Side Investigation found that highway signs on Ohio bridges are inspected once a year in conjunction with annual bridge inspections. But thousands of other highway signs, those not on bridges, are inspected only every five years.
The three signs that blew away were installed in 2008 and last inspected in November 2012.
A spokesperson for ODOT said its bridge signage is inspected more frequently than the federal standards, which require bridge inspections every two years.
