Norfolk Southern’s Heartland Corridor is one of the most important freight corridors in the eastern United States, providing access between the Port of Virginia and the Midwest and into Chicago via Columbus, OH. As part of a public-private partnership, Norfolk Southern initiated a $190 million clearance improvement program, removing obstructions from 28 railroad tunnels and seven bridges, allowing the railroad to more effectively run double-stacked containerized trains along the corridor. The improvements shaved 250 miles off the mid-Atlantic to Midwest route, saving about a day’s travel time making its operations vastly more efficient.
STV performed construction management and civil and structural engineering along with rail design and inspection services for the modification of 5.7 miles of tunnels and three overhead bridges.
