Sections of Interstate 93 south of Boston were submerged Saturday as historic rainfall triggered flash flooding and temporarily shut down a portion of the Red Line, according to reports from NBC Boston and The Boston Globe.
The flooding, described by CBS News as a “1 in 200 year event,” brought traffic to a standstill and prompted flash flood warnings across the region. The extent of the disruption extended beyond roadways, with the Massachusetts Bay Transportation Authority (MBTA) temporarily suspending service on a segment of the Red Line due to water intrusion.
The current flooding has resurfaced questions about infrastructure preparedness in the face of increasingly severe weather events. Similar, though less extensive, flooding occurred in 1989 and 1993, prompting discussion about the need for improved drainage systems and emergency response protocols. Sources indicate that following the 1993 flooding, there were calls for preventative measures that were not fully implemented.
The National Weather Service has not yet released a comprehensive assessment of the rainfall totals, but preliminary reports indicate that several locations received more than three inches of rain within a short period. The rapid accumulation of water overwhelmed drainage capacity, leading to widespread inundation of roadways and low-lying areas.
As of Saturday afternoon, crews were working to pump water off of I-93 and assess the damage to the Red Line infrastructure. The MBTA has not announced a timeline for full restoration of service on the affected portion of the Red Line. State and local officials have urged residents to avoid unnecessary travel and to heed all flash flood warnings.
