A woman driving south on I-93 was killed near the exit of Boston’s O’Neill Tunnel on Feb. 12, when a metal manhole cover flew through her Honda HR-V windshield, struck her and landed outside the tunnel. She was identified as Caitlin Clavette, 35, an art teacher in Milton, Mass.
After the incident, from Friday afternoon through Sunday morning, up to seven crews at a time inspected 919 structures, working on I-93 from Somerville to Boston and inside the Central Artery tunnels.
