E131 Structures Overview

Typical Right-of-Way - Mailine

The original (and existing) mainline that runs from VT to Adams, MA sit mainly on wood H-frame structures. The proposed steel H-frame structures would improve the condition, but would also support the addition of adding the OPGW to the design which helps to address outages quicker in these remote areas of right of way.

Typical Right-of-Way - Tap Line

The original tap line that runs from Bear Swamp to Florida, MA also faces similar asset conditions that threaten the performance and reliability of the line. The proposed new tap lines would also replace the steel lattice and wooden structures to steel H-frame (as seen in the image shown below).
