CSX Transportation, Inc., has awarded Clark Civil and joint venture partner Parsons Transportation Group a contract for the National Gateway Initiative, Phase 2. The project team will re-construct 11 locations along a Class I freight railroad to accommodate the use of double-stack trains.

The project is part of a larger program designed to improve the flow and efficiency of rail traffic by increasing the use of double-stack trains across the country. The project team will design and build 11 different clearance improvements along 92 miles of track from Jessup, MD, through Washington D.C., and west to Martinsburg, WV. The project is currently in design and the team is reviewing ways to remove obstructions on existing active lines that prevent the use of double-stack intermodal trains. Their approach will include lowering and realigning tracks, raising bridges, and blasting and re-lining tunnel crowns to clear trackway.

One of the most challenging components of the project will be re-lining the 920-foot-long Harpers Ferry Tunnel, a 120-year-old passageway that connects Harpers Ferry National Historical Park and the Chesapeake and Ohio Canal National Historical Park. Up to 50 passenger and freight trains pass through the tunnel each day. The team will remove the portal cap and lining then re-line the tunnel for improved clearance.

The project is scheduled for completion in May 2015.
