Virginia Avenue Tunnel Replacement Project Parsons and joint venture partner Clark Construction are currently constructing a new tunnel system underneath Virginia Avenue, between 2nd Street SE and 12th Street SE. The two-track tunnel will replace CSX's current 110 year old single-track tunnel and allow double-stack trains to pass through. This reconstruction will eliminate a key pinch point on the heavily-traveled I-95 corridor railroad route. DC2RVA - DC to Richmond Southeast High Speed RailThe Project will identify specific rail infrastructure improvements and service upgrades intended to improve the travel time, service frequency, and on-time performance of passenger trains operating between Washington, D.C. and Richmond, VA. The Project also will assess the environmental impacts of these improvements and identify ways to avoid, minimize, or otherwise mitigate such impacts. Specific improvements to the existing rail infrastructure between Arlington, VA, and Centralia, VA, include: Corridor-wide upgrades to existing track and signal systems to achieve higher operating speeds, including curve realignments, higher-speed crossovers between tracks, passing sidings and grade crossing improvements. Corridor-wide improvements of train operating capacity to achieve higher passenger train service frequency and reliability, including additional main track along most of the corridor, and additional controlled sidings, crossovers, yard bypasses and leads, and other capacity and reliability improvements at certain locations. Station and platform improvements for Amtrak and Virginia Railway Express (VRE) stations.
