Some changes coming to the runways at LAX may bring delays for travelers and noise for neighbors over the next several years.
The federal government has mandated that every US airport increase the safety zones at the end of runways to bring an extra margin of safety for planes as they take off and land.
The improved runway safety areas will provide a buffer one in case a plane overshoots or veers off a runway.

Four Los Angeles International Airport runways will undergo construction over the next three years, but only one will be closed at a time, LAX officials said.
The process might be particularly challenging since the second busiest airport in the country has only four runways on 3,500 acres — similarly busy airports have four times as much space.
The $250 million project is expected to begin next Friday with completion expected by 2018.
