O'Hare International Airport has a new taxiway.
Taxiway Zulu, also known as Taxiway Z, opened Monday, officials from the Chicago Department of Aviation said.
It's part of the ongoing O'Hare Modernization Program.
Aviation officials said 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.
