Parkersburg Mayor Bob Newell says the state is investigating material that fell into the Ohio River during a bridge repair and maintenance project.
A video posted earlier this month on Facebook by an Ohio resident shows unidentified material falling from a scaffold underneath the Memorial Bridge into the river.
Newell says the West Virginia Division of Natural Resources is investigating the incident.
Teays River Construction of Cross Lanes did repairs and maintenance on the bridge from Aug. 4 to Aug. 13.
Teays River Construction owner Ron Hayes says no material removed from the bridge was supposed to go into the river.
