WARWICK, R.I. (AP) — Workers have begun installing the first of three emergency safety barriers at T.F. Green Airport.

The Federal Aviation Administration is requiring the collapsible concrete pad on the secondary runway to help stop any plane that might overshoot the landing zone.

The work is part of $250 million in improvements to the airport planned for the next few years. That work also includes lengthening the main runway by about 1,500 feet.

The barrier should be finished next week. It is designed to crumble when a plane goes over it and can stop a Boeing 737 traveling up to 61 mph.

A second zone will be installed at the other end of the runway next year and a third will be built at the end of the main runway.
