Project Details

  • Cleared 6 miles of an existing right of way and 4.1 miles of new right of way
  • Constructed 2.1 miles of transmission line overbuild above the distribution line along U.S. Route 1
  • Constructed 270 single-pole structures with 477 conductor wire
  • Installed 2,000 feet of underground transmission crossing under the York River Bridge
  • Installed an aerial crossing over the Maine Turnpike north and south bound lanes
  • Relocated 3,100 feet of existing transmission line

Lean, Innovative, and Unique Project Solutions

This project was challenged by large amounts of wetlands, the York River Bridge Crossing, heavily traveled U.S. Route 1, and endangered plant species. The Cianbro team employed various construction methods in order to get the job completed on schedule, with minimal interruption to traffic, and resulting in positive environmental compliance.
