With any luck your car stayed parked last night.
Otherwise you would have faced the traffic that flooded onto San Leandro streets as a result of yesterday's lengthy shutdown of Interstate 580 east.
The cause was a fatal hit-and-run that police are calling murder.
If you were caught on the highway, please share any comments and upload any pictures you may have taken.
If you were out last night and noticed the heavy traffic on Bancroft Avenue, East 14th Street and other major arteries, here's why.
Shortly before 4:00 p.m. on Saturday afternoon, an East Bay Paratransit van collided with a motorcyle near the Grand Avenue onramp of Interstate 580 East, according to police reports.
Authorities say the van, which carried no passengers, was driven by 31-year-old Eddie Hall of Oakland.
Police say the van ran over the motorcyclist, who was apparently a member of the Hells Angels. He has been pronounced dead but has not yet been identified.
The van dragged the motorcycle for several miles until it pulled over at the 150th Avenue exit.
Authorities say Hall attempted to flee but was arrested by Alameda County Sheriff's deputies.
The highway remained closed east of 150th Avenue until about 2:30 a.m. Sunday morning as police searched for clues.
Hall has been arrested on suspicion of felony hit-and-run and murder.
Traffic is now back to normal.
