Overview
This CM/GC commuter rail project features the construction of a 0.6-mile-long flyover bypass bridge with one new mainline track and has the capacity for a second track in the future. The overall bridge structure length, including retained fill approaches, is approximately 5,000 feet and rises to 36.6 feet. The bridge will allow passenger trains to cross over two existing CSXT mainline freight tracks. Maintaining grade separation will increase passenger train service capacity by decreasing 26 conflicts per day between passenger and freight train traffic. In total, the project corridor spans 1.8 miles with significant clearing, grubbing, and earthwork on the east and west sides of the right-of-way. The project has 2,700 feet of retaining wall structure, crash walls, drainage structures, utility relocations (e.g., fiber optics and petroleum fuel lines), track shifts, 8,000 feet of new mainline ballasted track constructed across the bridge structure that ties in with at-grade mainline tracks, and wayside signal improvements. The project is being built in a live track environment around 70+ daily CSXT and Amtrak trains.
