Modern and old suspension

[M3019C LPS20]

In New York City, a two-section (red and green) traffic signal was commonly suspended from a mast-arm set-up, in which is well known as the "wheelie." In the 1950s and 1960s, when signal equipment was modernized, a practice, in which was generally uncommon, was to upgrade a signalized intersection that had only one suspended traffic signal in service. The new and improved set-up used a Marbelite traffic signal cluster along with a newly installed mast-arm/guy wire set-up, in which suspended the entire cluster at the intersection. Additional heads were never installed. Below, are two pictures of a good example of an intersection that once used each set-up. At Liberty Av. and Georgia Av. Brooklyn, New York.

Original set-up. Unknown date at this time.
