AT EIGHT metres wide and weighing in at 14 tonnes, Xtreme Engineering trucked off the last piece of the puzzle for Queensland Energy Resources' shale concept project.

Under police escort and needing the front gate to be widened the big load eased out of the driveway of Xtreme Engineering yesterday morning.

Boiler maker and project manager Luke Lanzon said yesterday's load was the last of six which had seen his men fabricate 58 tonnes of steel for QER.

"We have been very fortunate to work with the QER team in delivering their concept project," Mr Lanzon said.

"We've got the gate body and feed bin going off today and then we'll be on site for the installation."

He said the project had been challenging but "conceptually interesting" and should be finished in a fortnight.

"The steel is all from Queensland with the majority of it from Gladstone," Mr Lanzon said.

The project required more the 1500 bolts and will help to keep the final 23 metre high structure upright.

The combined effort between Xtreme Engineering and QER has seen 40 to 50 local people working full time since November which Mr Lanzon said was great for Gladstone.

Although wide-load driver Ursula Brandon has "done a lot bigger" in her 30 years of escorting big rigs, she said her main priority for all of her jobs was to keep the public safe.

With Ursula out front and her flashing lights on, the big rig slowly took off taking up both sides of the road.
