Traffic north of the Golden Gate Bridge was snarled for hours Sunday night, after a motorist's crash caused their vehicle to burst into flames.

ABC 7 reports that the incident occurred at around 7:20 p.m. Sunday, on southbound 101 just north of Spencer Avenue in Sausalito.

The cause of the collision is still under investigation, according to KRON 4. What we do know so far is that a driver swerved up onto a sharply angled embankment near the Golden Gate Bridge, then slammed into an exit sign. The vehicle erupted into flames after that, apparently as a result of the impact.

The driver, who CBS 5 reports was the only occupant of the vehicle, died at the scene. Fire crews and officers with the California Highway Patrol fought the blaze, a struggle that closed several lanes of the freeway until early Monday morning.
