The Massachusetts Department of Transportation has completed manhole inspections on Route 1 after a state trooper spotted a loose manhole cover in Saugus.
A state subcontractor working on this section of road has been suspended, and MassDOT says the cover was likely loosened during work associated with a repaving project.
MassDOT says no other manhole covers were found to be dislodged.
It was just over two months ago when teacher Caitlin Clavette was killed when a manhole cover on I-93 in Boston became dislodged and slammed into her windshield.
Authorities say they immediately responded to the Saugus location Wednesday morning and welded the cover to the frame.
The Massachusetts Department of Transportation wants a full report from Tango Construction to try to figure out what happened.
Tango Construction of Fitchburg declined to talk about the incident.
