Nighttime shots can be challenging, but when they work, they're just as rewarding. They're very often artificially lit, which poses all kinds of problems. In this photo the main source of illumination was from the street lamps, which were much lighter than the rest of the image.
One option would have been to crop them off, but in this case the sky lit by the dwindling light of the setting sun would have disappeared from view. So I chose to include the lamps, which in the end became a strength in the photo rather than a weakness.
With the constant stream of cars it was easy to form two white streams of light from the lights of the incoming cars and two red streams from receding cars. At least I'm quite happy with this.
