SAN FRANCISCO (CBS SF) — A woman believed to be in her 60s was being taken to a hospital Saturday night after she drove her SUV about a half-mile in the westbound lanes of eastbound Interstate Highway 80 on the San Francisco-Oakland Bay Bridge, the California Highway Patrol said.

First reported just before 7 p.m. Saturday, when the CHP was told of a wrong-way driver in a tan SUV had gotten onto the upper deck of the Bay Bridge from the Harrison Street.
