Welcome To Hamilton – (HDR/Tone-Mapped) by jwvraets on Flickr.A través de Flickr: ***For best results, click on image to view on black*** As you head North on McNab Street in downtown Hamilton, Ontario, you eventually need to cross the railway tracks serving the downtown train station as well as being a major East-West rail traffic route. On McNab, the solution was to go under, not over, the tracks. Over time, the underpass has been decorated by local artists, although perhaps not in an official manner. Sitting near the railway station, I assume that the artistic community felt a greeting to visitors was in order and hence the title of this image. The title is taken from the text in the yellow ‘box’ centred above the stairs which greets all with ‘Welcome To Hamilton’ and then in a very helpful manner, provides a number of arrows indicating directions from that point to some of the major destinations in the core. Over time the walls of the tunnel itself have been decorated and tagged and the whole tunnel has become a bit of a surreal entrance to the downtown core.
