Old Dominion/Vepco 500KV transmission line running along a 230KV line in Fredrick County, Maryland

This specific 500KV line is one of the oldest on the Dominion/Vepco grid, having been built in the 1960s. The towers also utilize weathered lattice, a practice that has been abandoned long ago due to weathered lattice corroding more easily. If I’m not mistaken, the transmission line was originally built by VEPCO but the ownership was transferred to Potomac Edison, (A subsidiary of FirstEnergy). All of the other 500KV lines built in the same era have been replaced with new 500KV structures and stringing, making this one of the last of its kind. It is expected to be rebuilt in the early 2030s.
