In Bucksport from the Orrington municipal boundary westerly to the Penobscot River, the project will involve the construction of new 345 kV and 115 kV transmission lines and the rebuilding of an existing 345 kV transmission line.

The existing 345 kV transmission line will be removed from its existing structures and placed on H-frame structures averaging 75 feet in height on the southern side of the corridor. At the Penobscot River Crossing, a steel lattice tower approximately 350 feet in height will be constructed in order to achieve the necessary clearances across the river.

The new 345 kV transmission line will run on H-frame structures averaging 75 feet in height. As the line nears the Penobscot River, two new steel lattice towers will be installed, similar in size and style to the existing lattice towers. One structure will be 124 feet in height, and the structure nearest the river crossing will be 360 feet in height. These steel lattice towers are needed to achieve the necessary clearances for crossing the river.

The new 115 kV transmission line will be constructed on H-frame structures averaging 55 feet in height on the northern side of the corridor for approximately 0.6 miles. From that point to the Penobscot River crossing, a distance of approximately 0.5 miles, the new lines will be installed on the existing lattice tower structures.

From the Bucksport Substation northerly along the Penobscot River for approximately 0.4 miles, two 115 kV transmission lines currently run on a single set of steel lattice towers approximately 100 feet in height. These structures will be removed and the two lines will be placed on two separate sets of structures, which will be a mix of monopole and H-frame style structures ranging from 56 to 130 feet in height.
