THOMASTON - The Long Island Power Authority (LIPA) is getting ready to dig up part of a road in the Village of Thomaston to install new power lines, but the project has raised a bit of controversy.The utility wants to dig a trench along Shoreward Drive that's two feet long and three feet deep to install a mile-long transmission line. However, Village Mayor Bob Stern says the project will permanently damage the asphalt. He insists that if LIPA wants to excavate, it should repave the entire road after. The utility argues that the demand is unreasonable. As a state authority, LIPA says it doesn't need the mayor's approval. The work is set to begin in May and will last one month.
