INDUSTRY, Calif. (AP) — The nation's largest landfill outside of Los Angeles where 130 million tons of garbage has been dumped is closing after more than a half-century of service.

The 630-acre landfill that served as a regional waste facility is shutting its gates Thursday because a permit for the site, which is nearly filled, expires on Halloween.

The landfill has accepted more than a third of Los Angeles County's trash and stands as high as a 40-story building.

Future garbage from the county's 88 cities will be put on trains to an abandoned gold mine more than 200 miles away.

The landfill will likely be turned into a park that will connect to existing hiking trails.
