High rise truss arms in Long Beach
|
All of the Pacific Coast Highway (Highway 1) within Long Beach is lined with these lights. These poles were installed in 1970 using 700w mercury vapor lights (and some 400w HPS). They were all changed to LPS at some point. Today the luminaires are M400A2s, 250w HPS.

The signal poles were concrete and used to have truss-arm attachments for the overhead lights in the 1980's, matching with the lamp poles, but when all of the signal poles were replaced with aluminum poles, CalTrans inexplicably did NOT use the same truss arm attachments for the overhead lamps to match the truss arm attachments for the concrete lamp poles.
If it were in my power, I would replace the overhead lamp single point mast arm attachments on the signal poles in PCH with truss arm mast arms attachments, to match with the lamp poles.
I also remember that the median mounted left turn signals on PCH and 7th, which had been there since 1983, were replaced with an overhead left-turn signal just last month. I wonder why these median mounted traffic signals are being replaced.
About the truss arm signals, I agree. There are a few truss arm signals in downtown Long Beach on Ocean St, I am sure you are familar with these.
So you would remember what sort of signal and lamp attachments were used in Long Beach circa 1980? (Those are my earliest memories of traffic signals)
Which ones were used at Ocean Boulevard and Terminal Island Freeway, and Seventh and Bellflower?
