BOISE, Idaho -

The Idaho State Historical Museum will soon undergo an expansion that will add about 13,000-square feet of exhibit space, allowing objects that have been in storage to go on display.

However, the work will close the museum in Boise for about three years.

Museum Director Jody Ochoa tells the Idaho Statesman the museum will close on Aug. 4 and reopen sometime in 2017. Crews will spend the next four or five months moving artifacts out of the building and into storage.

The state appropriated $7 million toward the expansion while the nonprofit Friends of the Historical Museum and the Old Idaho Penitentiary will raise another $3 million for exhibitions and technology.

The layout of the museum after the expansion hasn't been determined. Ochoa says they plan a whole new look.
