IMG_0841
Made in Columbia, South Carolina, AMERICAN SpiralWeld structural steel uncoated pipe in 30- , 36- and 54-inch diameters were vertically installed end-to-end in welded pairs, driven 60 to 90 feet in the ground, filled with rebar and concrete, and capped with concrete slab to form the subfoundations for 53 of the piers or “bents” that will support the mainline Port Access Road. Concreted pier columns are visible in the background.

When the Hugh K. Leatherman Sr. Terminal opens in North Charleston in 2021, container traffic traveling to and from it will use the new Port Access Road, a direct route from I-26 that will reduce the need for commercial trucks to use local roads. Supporting the mainline road’s foundation piers will be South Carolina made spiral-welded structural steel pipe installed as vertical piles driven 60 to 90 feet into the ground. Spiral-welded steel will also be used in the subfoundations of associated new bridges and roads.
