HPS Underpass Lighting

Here's a shot of a HPS underpass light, I'm not sure who made this style of wallpack but I've seen them on some older underpasses here. They use plastic diffusers instead of the more common glass prismatic refractor. There used to be a lot more lumes in here too...you can see some of the bypassed junction boxes and marks on the wall from the old lumes.

Here's a shot from '68 showing this exact underpass shortly after the freeway above was widened(401/Bayview).
