Early 1970's 115-kV Steel Monopole Transmission Line in Waterbury, CT
Here is a 115-kV steel monopole crossing Robbins St in Waterbury. This short line traverses from Freight St to Bunker Hill substation.
My estimation on the age of these poles is that they were built sometime in the 60's or early 70's, either as a new line then or replacing steel lattice towers. I'm leaning more on the latter because there's a steel lattice tower in the middle of Route 8, which is where across the river that the Freight substation resides.
I always thought these closed-circuit poles looked impressive, especially the double pole corner ones! I also noticed these particular monopoles contain ladders, which I find adds to it's unique appearance. I've always liked the "menacing" look of these (or any anti-sway bracket construction).
Update!: Thanks to using HistoricAerials(dot)com, I found a 1970 and 1972 aerial photo of the area this line is in, and in 1970 there seemed to be lattice towers of some sort throughout the line. In the 1972 photo, the line was completely rebuilt with these monopoles and even noticing the double corner poles with a bit of detail. To confirm, these were definitely likely constructed in 1971-'72 somewhere.
