Historical Photos of Philadelphia's signals

[traffic light guy]

I'm not a trolley guy, so ignore the trolleys in the pictures. I'm a traffic lighty person, today I'm gonna show old photos I found of traffic lights across Philly. I'm gonna show the history of the intersections and compare to how they look today.

It looks like Philly's signals were once green, before they went yellow. You can see a pedestal mounted set of Crouse-Hinds art decos.

Eagle signals and 3Ms mounted on mast-arms. The signals themselves were probably installed around 1974. But the photo was taken in the 70s. But they got replaced by McCains in 2011. The 3Ms were removed long before these were gone, same with the DW/W peds. Here's what the intersection looks like today (Scroll the timeline to 2007 to see the old signals, half of the original heads have been swapped)

This is one of the few circumstances where all the original equipment remains. These signals are all on pedestals.
