A seven car accident caused lengthy backups on the Braga Bridge Wednesday morning.

Massachusetts State Police tell WBSM news it's believed one car hit another at around 7:23 a.m. causing a domino effect chain reaction.

Four vehicles were towed from the scene.

A Tremblay's school van, with one child aboard, was involved but that child wasn't injured and no other injuries were reported.

State Police say the scene was cleared around 8:45 a.m.
