Crews Implode Old Highway 109 Bridge In Gallatin

CREATED Apr 25, 2014
GALLATIN, Tenn. – Crews imploded the old Highway 109 Bridge in Gallatin on Friday morning.

Traffic was stopped along the newly constructed bridge as the old one was brought down into the Cumberland River just after 8:30 a.m. 

“It wasn’t ten minutes after they stopped traffic we heard the explosion," said Ron Richardson who owns Ron's Automotive near the bridge's Gallatin side. “It kind of had a vibration to it when it blew.”

Demolition crews used explosives to bring down the truss-style bridge that was built in the early 1950's. A dozen emergency boats were standing by in the water. Throughout the day, divers will be busy working with cranes to remove the rubble.

“It’s connected to buoys and those buoys will tell the cranes where the debris is so they can go in there. They can pick it up," said TDOT Spokesperson Heather Jensen.

The old bridge had shown signs of aging and had been listed as structurally deficient. 

The Tennessee Department of Transportation began construction a new $29.5 million concrete and steel bridge in 2011. It was built beside the original structure.

A lane in each direction opened in March, and the remaining two lanes are expected to be complete by fall 2014.

TDOT said approximately 16,500 vehicles travel the bridge every day, but that number is expected to reach 30,000 by 2035.
