Deputies said 58-year-old Essie Grissom of Muskegon Heights was westbound in the right lane of the highway when she drifted into the left lane. A car in the left lane honked a horn, alerting Grissom who then overcorrected while going back to the right lane, lost control and overturned her sport utility vehicle into a ditch.
Grissom was taken to Hackley Hospital in Muskegon with non-life-threatening injuries.
At 8:40 p.m. and 2 miles east of the first scene, a tanker truck and a car collided.
Deputies said the truck, driven by 63-year-old Roger TenBrink of Whitehall, slowed down for the backup from the first crash. The car, driven by 28-year-old Alton Corbin of Grand Rapids, did not slow down in time and hit the back axle of the truck, police said.
Corbin and a front-seat passenger in his car, 32-year-old Melinda Vincent of Grand Rapids, were pinned in the car and extricated by Polkton Township firefighters.
An AeroMed helicopter crew flew Corbin and Vincent to Spectrum Butterworth Hospital in Grand Rapids, where Corbin was listed in serious condition this morning.
Vincent was in fair condition, a hospital spokesperson said. TenBrink was not injured in the crash.
Deputies had to close westbound I-96 for the helicopter to land for the second crash, as well as the investigation and clean-up work. Police reopened the westbound lanes around 11 p.m.
