At least one person was injured Tuesday morning in a four-vehicle crash in Peabody, Massachusetts.
State police said the crash happened on Interstate 95 southbound near exit 4.
Multiple lanes were expected to be closed for some time until the scene could be cleared.
Further south on I-95 in Wellesley, another crash happened at 6:30 a.m. near Route 9, which caused more traffic backups.
The extent of the injuries is unclear.
Both crashes are under investigation.
