Artists climb out onto the side of this bridge over the Colorado River to paint changing tags, declarations, and images on its side, and occasionally Union Pacific paints over it. The bridge art is visible facing east along Cesar Chavez Street, to drivers coming across the Lamar Bridge, and from foot when crossing the Pfluger Pedestrian Bridge. The graffiti has ranged from statements of support for Ron Paul's presidential campaign, to Pac-Man homages and marriage proposals, with some the result of collaborations between local street artists and taggers. The city's official line is that the bridge is the private property of Union Pacific and any graffiti removal is done by the railroad.
