Police said the woman, in her 30s, apparently jumped off an overpass near Mile Post 18 in Greenwich Township and that her death appeared to be a suicide.

The incident occurred about 9:30 p.m.

Investigators are awaiting the results of an autopsy to determine if drugs or alcohol were a factor and to establish the woman's identity.
