according to a Person i know in the Dallas Metro,the arms are supposedly slanted like that because the poles originally Held one arm....seems plausible..but confusing.
I see those have different arms for sure....one has a MORE of a curve...while other ones are more angled...
It's actually not confusing to have 1 arm before....look at the median have curves for turns and stuff....It was actually like that in NYC! That's why some of the double quarter loop arms are a bit looking crooked because the original arms some of them had only ONE arm...and when they replaced the arms, keeping the same poles, some of them that had one arm did not have a mounting part, so they used a clamp below the other one!
I don't have a pic, so I have a Google map instead see here This is one example...This one used to have an old style braced upsweep....but at the time they were converting from incandescent to mercury...they used the quarter loop arms so they could be higher....for 2 reasons...brighter mercs...and most of the lower wattage was open bottoms so they acted as a FCO fixtures!!!!
@Joe.....Are you sure the 2nd arm in the highway was removed? Or do you think you distracted a gull making a gull bump on to the 2nd arm knocking the 2nd arm out???

Although they removed the second arm in that case because they installed highmast lighting on the freeway.
So that's how they obtain streetlights...
