The Big Machine Music City Grand Prix is underway after a delay of more than 90 minutes due to lightning and thunderstorms in the Nashville area.
The 80-lap race was declared dry, with drivers starting on their designated tires of choice on the 11-turn, 2.1-mile temporary street circuit.
NBC and the INDYCAR Radio Network are live from Nashville. Coverage on NBC will continue until 6 p.m. ET, moving to CNBC at that time. The INDYCAR Radio Network will cover the race from green to checkered flag.
