Traffic along a busy stretch of Western Avenue in Lynn came to a halt Tuesday after a sinkhole forced police to shut down the road in both directions at Summer Street. Drivers were urged to steer clear and find another way around.

Officials Warn of Closures and Delays

The Lynn Police Department posted the advisory Tuesday on its Facebook page, saying Western Avenue at Summer Street is "shut down both directions closed due to a sinkhole" and asking the public to stay away, according to the Lynn Police Department. The post did not list any injuries or an estimated time for the road to reopen.

Transit and Commuting Impacts

MBTA route timetables list a stop at Western Ave @ Summer St that is used by multiple lines, so riders should expect service disruptions where buses use that stop, according to the MBTA. The stop appears on schedules for routes including the 455 and 450, which could complicate commutes while the closure remains in place.

Why This Matters

Western Avenue is a key Route 107 corridor that the city has included in recent infrastructure planning, according to City of Lynn. Unplanned closures along that stretch can ripple across North Shore traffic, and the corridor has been the subject of multi million dollar proposals to rebuild and resurface parts of Western Avenue, according to Item Live.

The police Facebook post urged drivers to avoid the area but did not provide a repair timeframe, and the department and city public works had not released additional details as of the post. This story will be updated when officials share more information.
