The Heartland Corridor improvement project was one of the most significant Norfolk Southern reconstruction programs in recent memory. As a result of this $191 million public-private partnership, height clearances were increased at 28 tunnels, as well as seven bridges along a 380-mile stretch running across Virginia, West Virginia, Kentucky and Ohio. These improvements now allow the railroad to run double-stacked container cars through the corridor, while shaving 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.
