A woman died after ending up in the waters beneath the Indian Rocks Beach Causeway after an early-morning crash Thursday.

Deputies responded to a single vehicle crash on the Indian Rocks Bridge, at approximately 4:50 a.m.

According to deputies, a 1989 Jeep Wrangler, driven by Robin Smith, was heading eastbound over the bridge. The vehicle struck the concrete guardrail on the bridge and overturned coming to rest on the driver side on the drawbridge portion of the bridge.

According to a witness, Smith exited the wrecked vehicle, walked to the south side of the bridge, climbed over the railing and jumped into the water.

Deputies and fire rescue units initiated a water rescue. A short time later, Smith, 49, was recovered unresponsive from the water by Clearwater Fire Department. She was transported to a nearby dock and pronounced dead.

A dog was rescued from the crashed vehicle. The cause of the crash is unknown.

The westbound lanes of the causeway were reopened before 6 a.m. Eastbound lanes opened just after 9 a.m.
