Narita International Airport Corp. is making improvements at the nation's main international gateway to prevent accidents involving planes going the wrong way while taxiing to and from runways, according to company officials.
The company, which operates Narita airport near Tokyo, plans to rebuild or eliminate some taxiways and improve traffic signs for pilots by spring 2006, they said Sunday.
The cost is expected to total about 2 billion yen.
The company plans to straighten a meandering taxiway near the main runway and eliminate five confusing taxiways nearby.
It will also reduce the number of other taxiways with complicated junctions, they said.
In March 2001, Narita's runway was temporarily closed after a plane that had landed took a taxiway under construction. Last July, two planes almost ran into each other on a taxiway near the main runway.
