Bridge Viewed From Below

　　I'm currently working as a company doctor in a huge manufacturing company. I'm entrusted with keeping all employees healthy and secure and I regularly patrol various workplaces, checking harmful particles in the air and organic solvents like toluene.
　　The following pictures show a bridge under which I passed on the way back. I used to be indifferent to such a structure itself before I became a company doctor, but I wasn't what I used to be. I was interested in the path added under the bridge for maintenance work. I was gazing at the small parts of the bridge until the ferry boat passed under the bridge.
