INDIANAPOLIS — One person was killed and two were seriously injured in a crash on an I-465 ramp on Indy’s west side Thursday morning.

The crash happened at about 5:15 a.m. on the ramp from southbound I-465 to Washington Street.

Indiana State Police said a preliminary investigation found that a SUV was headed southbound on I-465 approaching the ramp to Washington Street when the driver failed to navigate a curve in the ramp, continued straight through a grassy ditch, hit the embankment for the onramp and became airborne. The SUV then landed on the other side of the onramp, overturned and came to rest upside down.

Two occupants were ejected from the SUV, including a male who was pronounced dead at the scene, ISP said. Two people with serious injuries were taken to an area hospital.

The ramp from Washington Street to I-465 southbound was closed for about six hours while the crash was investigated.

State police noted that the investigation into the crash is ongoing, and test results for impairment are pending.
