(KRON/BCN) — Two parents died in a single-vehicle collision on Interstate Highway 580 Sunday morning east of Altamont in unincorporated Alameda County, according to firefighters.
The incident was reported on eastbound Highway 580 west of W. Grant Line Road at 10:38 a.m.
The vehicle may have hydroplaned on pooling water before it rolled over multiple times and came to rest down an embankment, according to Battalion Chief Stephanie Radecke with the Alameda County Fire Department.
A man and a woman were both pronounced dead at the scene. Two children, ages 5 and 6, were transported to a hospital. One of them suffered traumatic injuries, Radecke said.
Further information about the extent of the injuries was not immediately available.
