Looking this good isn't cheap.

The Holmberg pedestrian bridge, an architectural gem along the city's riverfront, is proving to be a continual drain on the city's maintenance budget.

The glass bridge connects the Bluff View Art District with Walnut Street.

In 2007, the city shelled out about $25,000 to fix seven panels, according to newspaper archives. And this year, the city spent about $10,000 on repairs.
