One person was killed and another injured in a crash along westbound Interstate 90 between Portage and Lake Delton, according to the Wisconsin State Patrol.
The crash was reported at 6:25 a.m. Wednesday at mile marker 98.
Investigators said the driver, Peter J. Miller, 58, of Racine, drove into the median for unknown reasons, over-corrected and lost control. The car crossed both westbound lanes, went into the right ditch, rolled over and landed on its left side.
Miller was extricated from the car, according to the release.
