The second of two 150-ton turbine runner assemblies for the expansion project at PPL Holtwood is scheduled to begin its journey Wednesday from the Voith Hydro facility in West Manchester Township to the hydroelectric plant. It will follow the same slow-moving, four-day route that was used in February for the shipment of the first turbine runner assembly.

Escorted by state police, the 24-foot-wide tractor-trailer will be traveling about 4 mph between 7:15 a.m. and 7 p.m. daily. Signs and traffic-control personnel will be stationed along the road to alert motorists about potential delays and direct traffic through local detours around the tractor-trailer.

The journey begins on Route 182 southbound to Route 74 south, crossing the Susquehanna River into Lancaster County on the Route 372 Norman Wood Bridge to Pinnacle Road. Before crossing the bridge, the runner assembly will be transferred to another trailer, which is nearly twice as long as the first, to better distribute the weight of the heavy load.

After crossing the bridge, the load will be transferred back to the original trailer for the final leg of the journey.

The runner assembly, which will be parked off Pinnacle Road on Saturday, is expected to arrive at PPL Holtwood Monday.
