GUILDERLAND — On Sunday evening, a car leaving the Northway on the ramp to Crossgates Mall careened through the guide rail and off the overpass, landing on the Thruway beneath, according to state police.

An SUV was traveling north in one of the two lanes where the car landed and, when it struck the car, turned over, according to a press release from the state police.

Four people were in the SUV and four people were in the car that didn’t handle the curve on the ramp. All eight were taken to Albany Medical Center — three with serious injuries, listed in critical condition.

“To my knowledge there has not been a similar crash in that area,” Trooper Stephanie O’Neil told The Enterprise.

“The crash is currently under investigation,” O’Neil said on Wednesday. “No names will be released by myself unless charges result from the investigation. All three critically injured individuals were still listed as critical but stable.”

Troopers responded at about 7:21 p.m. and all northbound lanes of the Thruway as well as the Crossgates ramp were closed for about eight hours to remove the vehicles and to investigate, the release said.
