SOUTH WHITEHALL TWP., Pa. -

The historic Wehr's Mill Covered Bridge in South Whitehall Township is closed until Lehigh County officials determine if the bridge was structurally compromised.

Police said the bridge was closed after a tractor-trailer weighing four times the 10-ton legal limit, passed over it on Friday.

Police said it's possible the bridge is still safe for travel, but want Lehigh County inspectors to make a formal determination.

Police said they are investigating to determine if the tractor-trailer driver should be cited.
