The cap is going back on Old Capitol in Iowa City at this hour. Gusty winds threatened to halt the project to use a giant crane to lift the 12-thousand pound golden dome atop the landmark, but University of Iowa crews say it’s safe and are going ahead. Project manager Gary Nagle says he’s been a bit iffy on today’s task because too much movement by the wind can make it dangerous.The historic Old Cap’s cupola, dome and bell tower were demolished in a fire 15 months ago that caused some six-million dollars damage. The new gold leaf-covered dome should be in place by one o’clock.
