How Regional Coordination Is Helping to Move ‘Superloads’ to Homer City

By the time a piece of equipment bound for the Homer City Energy Campus reaches a road in Southwestern Pennsylvania, the majority of its journey is already behind it. 

The equipment reflects a supply chain that stretches far beyond our region. Turbine components began their journey at GE Vernova’s facility in France, crossed the Atlantic Ocean to Mobile, AL, and then entered the nation’s inland waterway system. From Mobile, equipment traveled by barge through the Tennessee Tombigbee Waterway, Mississippi River, Ohio River, and Allegheny River before reaching Schenley in Armstrong County. Only then can the “homestretch” of the journey finally begin. 

This final portion may only cover a fraction of the total venture, but moving equipment of this size through Southwestern Pennsylvania presents an entirely different challenge. The first superload to leave Schenley last month measured 205 feet long, 17 feet wide and weighed 381 tons. Its path crossed Armstrong, Westmoreland and Indiana counties en route to its final destination in Homer City. 

As the former Homer City Generating Station undergoes a major transformation, the series of deliveries is only just getting underway. The plant, once Pennsylvania’s largest coal burning power station, was permanently decommissioned in 2023 after nearly 55 years of operation. The site is now being redeveloped as the Homer City Energy Campus, which will include a large natural gas power generation facility designed in part to support datacenter development. 

Getting the equipment there is an operation of its own. 

During September and October, Edwards Moving and Rigging is transporting 15 heat recovery steam generators to the site. The individual units can weigh between 228,000 and 438,000 pounds, even before considering the specialized equipment used to move them. 

Once a superload reaches the road, nearly everything around it must be adjusted. The transports can occupy two lanes and create rolling traffic slowdowns and temporary detours. Pennsylvania State Police, escort vehicles, and bucket trucks accompany the convoys. Crews may need to raise utility lines, move traffic signals, or clear up other overhead infrastructure before a load can pass.  

PennDOT has advised motorists that the transports generally move between about 10 and 25 miles per hour, with slower speeds when necessary. In particularly constrained areas, the movement can slow to a crawl. 

That means a successful trip depends on much more than finding a road capable of carrying the load; bridge conditions, construction projects, local traffic, utility infrastructure, and community schedules are all variables in this equation. A movement through one municipality can affect another farther down the route hours later. 

“The more information you have, the better planning you can do,” said Sara Walfoort, Freight Planning Manager at the Southwestern Pennsylvania Commission (SPC). 

That need for information is right where SPC fits in. 

SPC doesn’t drive the trucks, operate the barges, or issue the permits that allow the superloads to travel. PennDOT handles the roadway side of the movement, while Edwards manages the physical transport in coordination with Homer City Generation, law enforcement and traffic control personnel. River transportation brings in another set of partners, including the U.S. Army Corps of Engineers and the Port of Pittsburgh Commission.  

“We communicate, we facilitate, and we educate,” Walfoort said. “And that’s what we did.” 

As the region’s planning organization, SPC regularly works across county and municipal boundaries and maintains relationships with agencies responsible for different parts of the transportation network. Its freight program also treats highways, railroads and rivers not as isolated systems, but as pieces of one network that must work together.  

SPC’s current planning program calls for continued coordination with the Port of Pittsburgh Commission and the U.S. Army Corps of Engineers, monitoring inland river freight and assessing the impacts of scheduled lock closures. 

These ongoing deliveries to Homer City provide a real example of why those connections matter. Through SPC’s work on the region’s waterways, staff were aware that scheduled work affecting a river lock could overlap with Homer City’s delivery window. Homer City’s team had already worked through the approvals necessary for the land portion of the movement, which crosses three SPC counties and two PennDOT districts. But PennDOT’s responsibilities do not include river operations. 

This is where SPC comes in to help connect the two sides. 

SPC was able to bring the potential scheduling issue to the attention of Homer City Redevelopment and the appropriate transportation partners before it became a larger obstacle. Major work is underway throughout the Upper Ohio River navigation system, including Montgomery Locks and Dam, as the Army Corps replaces aging lock infrastructure. 

On the other hand, this doesn’t mean SPC is directing the Homer City operation itself. Its role is only one part of a much larger effort that includes extensive planning and coordination by Homer City Redevelopment, Edwards, PennDOT, and numerous other partners. Rather than managing the movement itself, SPC helps connect information across agencies, communities, and transportation systems. 

SPC’s impact could be accurately defined as more of a “piece it all together role.” 

This can mean gathering reliable information, helping it reach the right people, and providing a safe space where government and transportation partners can better understand what is happening outside their own jurisdictions.  

A project of this magnitude, although physically located in Indiana County, still has consequences in the neighboring Armstrong and Westmoreland counties. Information shared through SPC’s regional network can help broaden awareness and support coordination among these communities that may otherwise see only the portion of the movement passing through their own backyard. 

The superloads make this usually unseen work to be quite visible in reality. A person standing along the route may see an enormous truck creeping through an intersection, utility crews working overhead, and traffic waiting for the convoy to pass. Behind that moment are months of planning and a transportation chain that began an ocean away. 

There may also be lessons from Homer City that extend beyond this project. Southwestern Pennsylvania’s rivers can move extremely heavy equipment much closer to its final destination before it ever reaches a highway. The Army Corps notes that water transportation can offer significant cost advantages for freight while reducing the amount of heavy cargo placed on roads. 

If more large energy projects are located in the region, similar transportation challenges could follow. Homer City has a real chance to provide a model for how water transportation, specialized highway movement, and regional coordination can work together in the years to come.
