The MBTA said no one was injured. Transit police responded alongside bridge inspectors and Blue Line officials.
"Following the inspection of the overpass and the operation of a test train, Blue Line service resumed at 6:40 PM with trains traveling at reduced speeds in both directions through the area," an MBTA spokesperson said in a statement.
The cause of the sinkhole, which the MBTA said occurred on a bridge on Byron Street, is under investigation.
