A mock city built so emergency workers can train for disasters is nearing completion in a central Georgia city.

The complex known as "Guardian City" in Perry will serve as a training facility for emergency responders from around the nation.

Officials say construction of the mock city, built at a former Northrop Grumman plant, is almost complete. The first exercise is planned for December, with about 40 Marines planning to work an earthquake response scenario.

The mock city will include a dual-track subway, a mile-long interstate, a floodable neighborhood and two blocks of demolished buildings.
