The taxiways will service the longest runway at Newark, which handles about 200,000 flights a year. The runway itself will be repaved and receive new lighting and electrical systems as part of a $97.3 million rehabilitation project scheduled to begin in early 2014.
The Port Authority said three of the new taxiways will allow multiple planes to stage for departure at the end of the runway, reducing takeoff delays. The other new taxiway will allow arriving planes to exit faster and get to their gates quicker.
The Port Authority estimates it will save 30 seconds per flight, which will have a cumulative effect toward reducing delays during the morning and evening peaks.
"The efficient movement of passengers and cargo through our airports is vital to the region's continued economic growth, and the port authority will continue to invest in projects that keep the U.S.'s busiest airport system running safe and on-time," said David Samson, chairman of the port authority.
The project will create 510 jobs, $34 million in wages and $152 million in regional economic activity over the 16-month work period, officials said.
