At nearly 400 tons, it's worthy of the title “superload.”

The oversized load — a steam condenser — is slowly meandering its way through Butler County today via Route 8 and Route 108 en route to a gas power plant outside New Castle.

The load along with a convoy of vehicles including trucks, police cruisers and a utility crew are part of the painstaking transportation operation.

The top speed, said one driver for Miller Transer of Edinburg, Ohio, which is moving the load, at best reaches “snail's pace.”

Holtec International of Turtle Creek, Allegheny County supplied the condenser, and that's where its journey began Friday.

The load previously navigated a number of roads in Allegheny and Westmoreland counties. The load on Sunday moved into Butler County and eventually came through Center Avenue and up Main Street in Butler.

The caravan made an overnight stop at the parking lot of the Belmont II restaurant next to the Kwik Fill at Route 8 and Mercer Road in Center Township before resuming the trek this morning.

“The load is just shy of 800,000 pounds and its spread out over 26 axles,” Trooper Chad Savannah said. “There's a truck in front pulling it and a truck in back pushing it.”

Along for the ride, he said, is a utility crew with a worker in a bucket whose job is to remove wires and traffic lights for the load to pass, and then replace them once it's through.

From Route 8, the load is headed onto Route 108 where it will travel through Slippery Rock, into Lawrence County and though New Castle before reaching its destination in North Beaver Township.
