Maintenance on Interstate 93 will require transportation officials to close the expressway through Boston two times per month beginning Tuesday on the northbound side.
Traffic on I-93 northbound will be detoured off the expressway at exit 16, Southampton Street, and directed along surface streets beginning Tuesday, June 18 at 11 p.m. and ending Wednesday, June 19 at 5 a.m., according to a state Department of Transportation press statement.
Traffic may re-enter I-93 northbound at the Haymarket on-ramp. Traffic headed toward Route 1 northbound (Tobin Bridge) should stay on surface roads and access the Route 1 northbound on-ramp at City Square, according to the statement.
