The Georgia Department of Public Safety is pointing to strap failure and not load securement as the cause for a massive lumber spill that snarled traffic on Wednesday.

The incident happened around 1:30 p.m. on southbound I-75 in Cobb County, Georgia.

No serious injuries were reported, but the incident did cause big traffic backups as crews worked to clean up the spilled lumber.

On Thursday, the Georgia Department of Public Safety took to social media to clarify that the lumber spill was caused by strap failure and not a problem with load securement.

The agency reminded truck drivers to check their straps for defects before use.
