Construction of the $25 million John M. Roll U.S. Courthouse in Yuma has been completed by Tucson-based Sundt Construction Inc.

The courthouse is named for the late Judge Roll, who was killed in the Jan. 8, 2011, shootings in Tucson.

The two-story, 57,000-square-foot building has two courtrooms and judicial chambers, detention cells and administrative areas for court personnel and the U.S. Marshals Service.

Sandstone and masonry cover the building's exterior and "living walls" of vines planted on steel trellises shade the windows.

In the entryway, a 10,000-square-foot canopy made of photovoltaic panels supplies shade while generating up to one quarter of the building's electricity needs.
