South Park Bridge - Salvaging parts from the old bridge

Parts of the old bridge will live on

South Park Bridge leaf removal

Removal of the South Park Bridge's north leaf took place on Thursday, Sept. 2, 2010. The south leaf of the bridge was removed on Tuesday, Aug. 31.

Each span weighed 221 tons. Some of the bridge span metal will be recycled, and some will be used on the new bridge. Removal of the first span took 7 hours as the bridge beams were laminated and the acetylene torch would lose its 'cut' line for each layer. Removal of the second span or 'leaf' only took a couple of hours as they used a magnesium torch fueled by pure oxygen which burns at 4200 degrees. The process was that the lower supports were cut at the same time to maintain balance. Then the upper supports were cut and the leaf was lowered to a barge, where it was moved to another site for salvage and recycling.

County will salvage gears, engine, and other elements

The old South Park Bridge will soon be gone, but it won't be forgotten—especially the parts that will reappear in new settings once the new bridge is built (learn more about the funding effort for the new bridge).

The demolition plan calls for many parts of the old bridge to be salvaged and reused, including the drawbridge gears, which will be incorporated into the pedestrian rails of the new bridge.
