INDIANAPOLIS -- IndyCar will make its debut at Circuit of the Americas in Texas and return to Laguna Seca, California, as part of its 2019 schedule.
The 17-race schedule released Tuesday drops Phoenix and Sonoma, California from the calendar.
The Texas track in Austin replaces Phoenix in March as the second race on the schedule. The road course opened in 2011, hosts a Formula One race and, at 4.048 miles, becomes the second-longest circuit on IndyCar's schedule.
Laguna Seca hosted 22 open-wheel races until 2004. The road course near Monterey was last the site for an Indy car season finale in 1996.
