The Los Angeles Fire Department rushed to Wilmington after a tunnel collapsed and trapped 27 people inside. Four other workers went in after the collapse to help the others. The construction workers inside the underground tunnel were rescued roughly an hour after the collapse,

Workers were 400 feet (121 meters) underground and as much as 6 miles (9.6 kilometers) inside from the only entrance when the cave-in Wednesday evening threatened to trap them on the far side of the tunnel’s boring machine,

Los Angeles Fire Department Capt. Danny Wu explained the efforts by first responders to rescue at least 31 workers after a tunnel collapse in the city.
