St. Louis, MO (KSDK) - Police are continuing to investigate what caused a motorist to lose control of their vehicle, crash on Interstate 64 early Wednesday, then flee the scene before officers arrived.

The incident occurred early New Years morning on eastbound I-64 at the Tower Grove overpass east of Kingshighway.

Authorities are not certain whether the driver involved crashed while on the highway, or if the car somehow crashed into the interstate from Tower Grove Avenue.

The crash blocked eastbound traffic on the highway for more than an hour. No other information was available early today.
