In my later teens I was living not too far from this area (also known as Weymouth Landing) and I fondly recall the neat architecture of Massachusetts Electric Company's local electric distribution lines in this vicinity and in surrounding towns. Interestingly, at some time during the 1920s the company started to use steel pins with unthreaded shanks that were tightly hammered into their creosoted crossarm's pin holes. They held very well! In addition, the company installed standard alunimum pole tags with their initials on the ends of all of their crossarms until around 1960, probably for identification purposes. Their arms also had a 1/4-inch diameter carriage bolt tightened near their ends. This practice likely was intended to reduce wood/crossarm cracking. This idea seems to have worked very well since I have seen many of their aged crossarms in exceptionally good physical condition!

The street lights in the above photo were made by General Electric and were known as the Form 400 style. They were introduced in 1955 and operated 400-watt mercury lamps. These fixtures were very popular across the United States as postwar business districts were rapidly expanding and an unprecedented network of highways were being constructed from coast-to-coast. All of these new improvements required updated light sources and mercury vapor was the number one choice by most planners and engineers.
