CSXT proposed an $842 million plan to raise roofs on bridges and lower some railroad tracks across the mid-Atlantic so that it could carry double-stacked cargo containers on its trains. The proposal is gaining steam because of its promise of clearing tractor-trailers off the region's congested highways and improving commuter train service.
It also would mean rebuilding some railroad bridges around the region, including the Virginia Avenue tunnel just south of the Capitol. Raising the roof of that tunnel alone would cost an estimated $140 million. The 12 other local projects proposed, including replacing the bridge on Deer Park Drive in Montgomery County's historic Washington Grove, would add millions more.
The freight company would pay about $393 million of the National Gateway initiative, while state and federal dollars would pay the rest. The project is seeking stimulus dollars for some of the costs.
