Remotely located and extending from the California-Arizona border into Southern California, the 155-mile, 500 kV transmission line project delivers more than 1,200 mW of renewable electricity to California. Aldridge drilled over 3,100 cubic yards of rock and poured more than 36,000 cubic yards of concrete in a timely manner for 2,115 foundations. The project included extensive environmental monitoring and protection measures for endangered plant, bird and animal species.
