Executive Summary
On April 24, 2019, about 2348, the towing vessel Edna T. Gattle was pushing the barge Terral 2 downbound on the Atchafalaya River through the Union Pacific Railway Bridge at mile 41.5, near Krotz Springs, Louisiana, when the captain lost control of the tow and the vessel and barge made contact with the bridge and piers. As a result, the barge suffered $26,748 in damages, and the bridge sustained $500,000 in damages and was out of service for 3 days. No injuries or pollution were reported.
Probable Cause
The National Transportation Safety Board determines that the probable cause of the Edna T. Gattle and tow’s contact with the Union Pacific Railway Bridge was the captain allowing the tow to proceed beyond a safe decision point without confirming the status of the bridge opening, given the high river current.
