Graffiti Cross

The Free Expression Tunnel is the longest, widest, and most heavily used pedestrian tunnel under the railroad tracks at North Carolina State University in Raleigh, North Carolina (also goes under Yarbrough Drive). The special aspect of the tunnel is that anyone is permitted to decorate its walls, ceiling, and floor. The tunnel connects NCSU's North Campus with the Central Campus and provides the most direct route from the The Brickyard to the Central Campus residence halls. Clubs, fraternities, sororities, and other organizations often paint the tunnel to promote events and amateur artists paint to express themselves and to promote freedom of speech. A retaining wall just outside the tunnel's south entrance is also open for free expression. The tunnel was open to free expression in the 1960s and was the university's response to illegal graffiti. The "service tunnel" itself was opened to pedestrian traffic in 1931, as denoted by a plaque at the north entrance.

I took this while at NC State in June. Was a very cool experience!
