PITTSBURGH (AP) - More than 1,800 knitters have covered Pittsburgh's Andy Warhol Bridge in 3,000 feet of colorful yarn.
Volunteers worked all weekend to attach 580 blanket-size, hand-knitted panels to the pedestrian walkways on the downtown bridge.
The project was organized over the last year by the Fiberarts Guild of Pittsburgh and other local institutions. The group says knitters from more than 80 Pittsburgh neighborhoods and 120 area townships signed up to help.
The guild calls it the nation's largest "yarn bomb." The term applies to artists who knit coverings for everyday objects like lampposts, street signs and trees.
A community arts and crafts party will be held at the bridge on Aug. 25. The bridge will be covered in the yarn until Sept. 6.
