Massive milestone on the move!

After more than a decade in storage, 120-foot-long, 463-ton wall beams are finally making their journey down the Tennessee River!

On Aug. 29, we began transporting the first of 12 upstream approach wall beams by barge from Watts Bar Dam to the Chickamauga Lock Replacement Project — a 7-hour trip marking a major step toward safer, more efficient navigation.

“These beams are a critical component... getting them to the site is a huge step forward,” said Project Manager Bob Winters.

Originally built in 2013, each beam is:
📏 120 ft long
🏗️ 10 ft high & wide
⚖️ ~926,000 pounds!

Thanks to incredible teamwork from contractors CJ Mahan and Barnhart, these giants are being safely delivered over the next few weeks.

With the upstream approach wall now 68% complete, the future of efficient navigation on the Tennessee River is coming into focus. ✅
