It turns out that that this is a detectable warning tactile tile, which helps visually impaired people find the end of the street and wheelchair users have access to get on and off the sidewalk. I am glad that City of Somerville is making efforts to make their sidewalks more friendly for the individuals that are differently abeled than myself. Isn't it amazing how much you take for granted, such as crossing the street safely?
A point to ponder is why haven't I noticed this tile elsewhere before? Possibly I only noticed this NEW change to the neighborhood, mostly because it effected the path I take to work and there could be longstanding ones in the Boston area that I have never noticed. It also makes me wonder what else I take for granted/ never noticed around my community?
What positive changes have you noticed in your neighborhood lately?
