State transportation workers with the help from prison inmates finished its latest sweep of the homeless campsite under Nimitz Highway viaduct near the airport which resulted in 400 cubic yards of trash being hauled away.

No one was arrested during the weeklong cleanup, which ended yesterday near Keehi Lagoon.

Tammy Mori, state Transportation Department spokeswoman, said 35 workers from her agency were aided by 45 inmates from Oahu Community Correctional Center.

Before the sweep began July 12, state sheriffs warned 30 to 40 people that they were living there illegally.

Mori said workers removed 400 cubic yards of trash from the homeless campsite. Also hauled away were 152 cubic yards of metal; 426 batteries; 130 tires; 21 propane tanks; and 66 shopping carts and other miscellaneous items.

In a separate action, the city on Monday evicted 200 homeless campers from Maili Point at an area known as "Guardrails." The Leeward Oahu sweep is part of the city’s efforts to clean up Oahu’s beaches.

A similar cleanup was conducted at the same Keehi Lagoon campsite by state transportation workers in January 2009. In that operation, state workers hauled away 108 truckloads of trash; 12 loads of metal; one load of batteries; 16 gallons of hazardous materials such as paint, propane and paint thinner; and 38 tires during an operation that took a week and a half.

The Keehi Lagoon site also was the area where police in 2007 recovered an abandoned car with several coils of copper wiring believed to have been stolen from Campbell High School’s football field.
