PROJECT DESCRIPTION: The applicant proposes to discharge 36 cubic yards of rock and 9,079 cubic yards of soil into wetlands and streams adjacent to Caney Creek, resulting in a total of 5.66 acres of permanent impacts to wetlands and waters of the United States and 1.58 of temporary impacts wetlands and waters of the United States. The proposed project will include constructing approximately 9 miles of second mainline track on the northwest side of the existing mainline track. With the proposed project, the applicant is requesting to construct bridges, culverts, associated structures and supporting infrastructure, such as access roads and drainage ditches. The proposed project will include modifications to existing structures and the construction of new structures, currently anticipated to include:
• Proposed bridge for the second main track and a replacement of the existing bridge structure for the existing mainline track at milepost (MP) 337.78 consisting of two new Pre-stressed Concrete Slab (PCS) span bridges with timber ties for a total length of 75 feet.
• Proposed bridge for the second main track and a replacement of the existing bridge structure for the existing mainline track at MP 337.58 consisting of two new PCS span bridges with timber ties for a total length of about 40 feet.
• Proposed bridge for the second main track and a replacement of the existing bridge structure for the existing mainline track at MP 335.77 consisting of two new PCS span bridges with timber ties for a total length of 58 feet.
• Proposed bridge for the second main track adjacent to the existing bridge structure for the existing mainline track at MP 334.66 consisting of a new Pre-stressed Concrete Box (PCB) span bridge with timber ties for a total length of 282 feet.
• Proposed bridge for the second main track adjacent to the existing bridge structure for the existing mainline track at MP 333.00 consisting of a new PCB span bridge with timber ties for a total length of 36 feet.
• Installation of one 36-inch-diameter and 22-foot-long Corrugated Metal Pipe (CMP) culvert extension at about MP 332.46 to convey drainage from the proposed ditch under the proposed second main track.
• Proposed bridge for the second main track and a replacement of the existing bridge structure for the existing mainline track at MP 332.04 consisting of two new PCS span bridges with timber ties for a total length of 60 feet.
• Installation of two 36-inch-diameter by 68-foot-long Smooth Steel Pipe (SSP) culverts at MP 331.56 to convey drainage from the proposed ditch under the proposed second main track.
• Proposed bridge for the second main track adjacent to the existing bridge structure for the existing mainline track at MP 331.15 consisting of a new PCB span bridge with timber ties for a total length of 72 feet.
• Proposed bridge for the second main track and a replacement of the existing bridge structure for the existing mainline track at MP 330.79 consisting of two new PCS span bridges with timber ties for a total length of 58 feet.
• Installation of one 36-inch-diameter by 78-foot-long SSP culvert at MP 329.83 to convey drainage from the proposed ditch under the proposed second main track.
• Installation of one 4.2-foot by 2.5-foot and 30-foot-long CMP arch culvert extension at MP 329.33 to convey drainage from the ditch under the proposed access road.
The applicant also proposes to install temporary erosion control measures during construction activities. Once the construction is completed the applicant states that all temporary erosion control measures will be removed, disturbed areas will be seeded and stabilized. The purpose of the proposed project is to provide a second mainline track next to the existing mainline track to create a bypass for through trains to move around local trains switching customers and expand train movement capacity within this corridor. The applicant’s plans are enclosed in 36 sheets.
