Rhode Island's tallest building will soon be its most visible symbol of the state's long economic decline.

The 26-story Art Deco-style building is losing its sole tenant this month. No one is moving in.

The building is the most distinctive feature on the Providence skyline, and it will no longer be fully illuminated at night, if at all.

It's a blow for the state, which had 9.4 percent unemployment in February and has had one of the worst jobless rates in the nation for years.

One real estate expert at Harvard Business School says the Superman building will become "the ultimate urban pothole."
