I would leave it as it is. It is a very powerful image, because everything is centered and because of the remaining asymmetries. The top lamps, in particular, are placed just at the classical 2/3 rule says. Of course, rules are made to be broken, but here the construction already breaks the rule that symmetry should be avoided. The position of the top lamps is just what is needed to balance the picture. That, and the sign on the right.
Actually, that picture works on two planes. On the first plane, you have the symmetry and the message of endless road which goes with it. On the second plane, you have the anchors of the top lamps and sign to guide the eyes of the viewer to explore the frame. The top lamp middle, the sign and the symmetrical point of the sign form an equilateral triangle. I find my eyes almost trapped in that virtual triangle, moving from the top lamps to the sign and then jumping to its symmetrical point which is empty so that I am forced to find something else and explore, then go back to the top lamps and starting again.
The picture may be improved by lightening it a bit, improving the contrast and removing the vignette.
