About an hour later, around 5:30 p.m., the transportation agency said the scene had cleared and all lanes were open again.
MassDOT said that in addition to the signage that is in place on the approach and at the portal alerting drivers of the height restrictions/clearance, there is an Over Height Vehicle Detection system in place that will be expanded under the upcoming 2024 Sumner Tunnel work.
Transportation officials also continue to evaluate ways to help mitigate the issues of over height vehicles going into the tunnel.
