Looking north along Broadway in Denver, near the Ellsworth intersection. The tall building with the angled roof on the right still stands today.

The heavy cables on steel pole in the foreground are Denver Tramway trolley power. You can see a few poles down where one of the conductors feeds over to the trolley wire down the center of the street. I presume that street lamp power comes from lines on the opposite side of the road, since I see no connections between the lamp and the trolley power conductors. (Makes sense - 600VDC isn't terribly great for street lighting.)
