Photographer Dan Galvin is a consultant to Broadway Curve Constructors, the joint venture of Pulice Construction, FNF Construction and Flatiron Constructors that is building the $776-million I-10 Broadway Curve Improvement project in Phoenix. Galvin provides five photos per week for the project’s website, so he is frequently recording construction progress on the site.

Galvin captured this image during a nighttime operation to set bridge girders for a flyover ramp. The area was lit only by two light plants, making the image a bit grainy and adding to the surreal look, Galvin says.
