CANTON -- The New York Power Authority is holding a public information meeting in Canton from 4 to 8 p.m. today on its plan to rebuild a 70-year-old transmission line from Massena to Croghan.

The meeting is to be held in the county Pubic Safety Building, 48 Court St.

NYPA spokeswoman Julieanne Sullivan said that landowners have been notified of the plans and have been notified of the Canton meeting, another meeting in Louisville yesterday, and another at the fire hall in Harrsiville, 14226 Church St., tomorrow from 4 to 8 p.m.

NYPA said it plans to spend $70 million replacing old wooden poles and towers with metal ones, and that the two-pole structures for parts of the line will be replaced with “monopoles,” taking up less room.

The lines run 85 miles from Massena, home to the St. Lawrence-FDR hydroelectric plant, to a substation in Croghan, Lewis County.

The 230 kV lines were built by the federal government in 1942 and were acquired by the New York Power Authority in 1953.

The route for all but eight miles of the lines travels on outmoded wooden structures that need to be replaced periodically. The new 230 kV lines on steel structures will sit on concrete foundations. All construction is expected to be on the existing right-of-way in order to minimize the impact on the environment and adjacent property.

Construction on the line is slated to begin in 2018 and last until 2023. When completed.
