O'Hare opens new taxiway

O'Hare International Airport has a new taxiway.

The Chicago Department of Aviation said Monday that it has opened Taxiway Zulu, also known as Taxiway Z. It's part of the ongoing O'Hare Modernization Program.

Aviation officials say the taxiway will provide a new route for aircraft to taxi to the terminal and cargo areas from O'Hare's northernmost runway. They say that means shorter taxi times and improved taxiing procedures, which will save fuel and reduce emissions.

Officials estimate the new taxiway will save about $12.7 million a year. It took two construction seasons to complete.
