CHICAGO — Seven vinyl banners draped this month along one of Chicago's most iconic bridges, advertisements some have dubbed "a visual crime" and "commercial graffiti," are reviving a debate about how governments raise money in tough economic times.

In the aftermath of the Great Recession, a public school district in Colorado is selling ads on report cards and Utah has a new law allowing ads on school buses. Chicago Mayor Rahm Emanuel's administration, straining to fill a $600 million budget hole, is looking to raise $25 million from ads on city property — including bridges, electrical storage boxes and garbage cans.Chicago Tribune architecture critic Blair Kamin called the bridge ads "a visual crime" and "a grotesque cheapening of the public realm."

The effort kicked off this month with Bank of America ads on the 81-year-old Wabash Avenue Bridge, which crosses the Chicago River and has appeared in movies including "About Last Night" and "The Dark Knight."

"I think it's disgusting," Chicago resident Linda Rosenthal said recently, shaking her head as she surveyed the signs. "The architecture in Chicago is stunning. To see this awful advertisement angers me."

The white ads with blue lettering and Bank of America's logo are posted on limestone bridge tender houses, which hold the equipment used to raise the bridge when tall boats pass beneath. Bank of America paid $4,500 to put seven signs on the bridge for about a month, said city spokeswoman Kathleen Strand.

Strand promised the city's new campaign will have "policies to protect the integrity of Chicago's facade" and likened the initiative to the Chicago Transit Authority bringing in about $20 million annually from abundant ads on buses and elevated trains that don't seem to anger anybody.

"The municipal marketing strategy is really about pursuing innovative opportunities to avoid having to cut city services or increase the tax burden on Chicagoans," Strand said.
