The 36 and a half metre beams weighing in at a whopping 78.5 tonnes each, had to get around the T-intersections on the ends of Bicentennial road, a mission which can take up to two hours per beam. 

Katherine transporting company Slingshot Haulage have been contracted to move 24 of the biggest beams in the NT from Darwin to a mega-prawn farm near Kununurra, Western Australia which crosses into the NT.  

The beams will be holding up a very large bridge. 

Operations manager of Slingshot Haulage Chad Dehne said Katherine should expect to see more of these huge beams traveling through every five days for the next two months. 

“Every time we hit a T-intersection we have pull over and tread really carefully,” Mr Dehne said. 

“We pull one truck to the side of the road, then the pilot team escorts the other around the corner and gets it to a safe place. 

“Drew drives the truck around and Neil “Scruffy” Gallagher walks behind steering the jinker with a remote control. 

“Then we get the next truck around,” he said. 

There are five intersections the team will have to negotiate on their two to three day trip, before turning around, driving back and repeating the process until all 24 beams are delivered to Kununurra successfully. 

The trucks travel at walking speed around the corner, but can build up to a maximum speed of 70 kmh along the highway. 

These are just the first of the concrete steel reinforcements made by All Cast Darwin, needed for what just might be the largest prawn farm in the world.
