Southold Town police say Helga Bauer was eastbound on County Road 48 at about 8:18 Friday morning when her car crossed over into westbound traffic and struck a utility pole.
Ms. Bauer, of Lake Ronkonkoma, was transported to Stony Brook Eastern Long Island Hospital where she was pronounced deceased, a police report states.
The morning crash resulted in a temporary closure of Route 48 near the intersection of Sound Road and Main Road. A Suffollk police helicopter was summoned and landed at Greenport High School where Ms. Bauer was transported via ambulance.
Southold Police Chief Martin Flatley said Ms. Bauer went into cardiac arrest and was sent to the nearest hospital, rather than flown via the medevac.
He said police did an accident reconstruction investigation at the scene while the road was closed. He said it was reopened at about 10:30 a.m.
The Greenport Fire Department was on scene at the crash.
