The Port of Longview (Port) constructed the Port's Industrial Rail Corridor (IRC) in the early 2000s to provide more efficient access to existing import/export facilities, to stimulate economic growth within Washington's Cowlitz County, the Pacific Northwest (PNW) and the country, and eliminate the negative impacts associated with at grade crossings in the local community.

The focus of this TIGER project is a further expansion of the IRC. The proposed IRC Expansion Project consists of relocating the original IRC north, to accommodate three new through tracks, 6 new sidings, and to allow for increased train clearance lengths of 8,500 feet and greater. These improvements will provide much needed unit train access and staging for current customer and future tenants on redeveloped and underutilized berths that are currently underutilizing the freight capacity of the Port.
