Overhead: The state-approved route consists of 45 miles of overhead lines including the reinforcement of existing 345- and 115-kV lines between Haddam and Milford. New 345-kV overhead lines will begin at the switching station in Middletown and travel along the existing right of way to the site of a planned substation in Milford connecting to a planned switching station in Wallingford into Milford. Structures will include monopoles or H-frames, depending on the width of the right of way.
