Dennis and Marilyn Funtal inched their way along the Andy Warhol Bridge Monday morning, stopping with every step to admire the 580 hand-stitched afghan panels that currently envelop the structure.

“Quite unusual,” Dennis Funtal said, “just like the City of Pittsburgh’s always been — unusual.”

The retired Brookline couple made a point to venture downtown Monday to see what's been called the largest “yarn bomb” in the United States. “Yarn bombing” is a form of street art, which unlike graffiti can be easily removed and doesn’t damage public property.

If a "yarn bomb" can be compared to a foot race, this one was a marathon.

Over the weekend scores of volunteers beset the Andy Warhol Bridge in Pittsburgh, affixing hundreds of pre-made, brightly colored yarn panels to the steel span.

But it was all months in the making, with hundreds of knitting and crocheting artists from across the region getting involved in the grassroots Knit the Bridge project.

Among those hanging panels on the bridge over the weekend was Pam Volz of Mt. Lebanon.

Starting August 10, one of Pittsburgh’s famous steel bridges will be getting a makeover when the largest “yarn bomb” ever in the United States blankets the Andy Warhol Bridge.

Amanda Gross, outreach coordinator for Fiberart International, is the lead artist of a project called Knit the Bridge, in which she and 1,267 volunteers from all over Allegheny County have spent the last year knitting panels to cover the bridge.
