Three cars were reportedly involved an accident just before the Skyway exit at the overpass around 8:26 am this morning. An older Ford Explorer was allegedly seen fleeing the scene after the accident. Authorities believe the driver that left the scene may have an injured arm. There's a large amount of glass and debris in the roadway and traffic is backed up to the E 20th Street. The west bound lane is blocked while Cal Trans crews are cleaning the dabris.
