Some shots of the Umberto I tunnel, which connects via Nazionale to via Tritone. The tunnel used to be pretty dingy and the air quality inside was horrible. It made you not want to walk through, even though it’s a nice shortcut to take. The tunnel was closed for repairs for quite awhile and reopened in its current state in September 2007. I always noticed how bright and white it was, but it wasn’t until looking up info for this blog post that I learned the paint has special properties that helps combate air pollutants. I guess that also explains why the air inside is much more pleasant! Good to see the city of Rome thinking about these things (well, at least they were when Veltroni was in charge).
