I-93 North at Exit 16 and related on-ramps will be closed overnight between 12:30 a.m. and 5:00 a.m. on Tuesday, July 21 and Wednesday, July 22. All traffic will be detoured at Exit 16 (Southampton Street, Andrew Square). In addition, ongoing pavement resurfacing, bridge deck and lighting repair will cause nighttime lane closures on I-93 North and South of Boston.
The detour for I–93 North will follow Frontage Road northbound to Atlantic Avenue and the I-93 North on-ramp near Seaport Boulevard. The I-93 North on-ramp at Essex Street will remain open. In addition the I-93 North on-ramps at Congress Street in South Boston, from I-90 East and West and at Mass Ave and Broadway will be closed and detoured.
This closure is the first of a more efficient Mass Turnpike Authority traffic plan. By closing segments of the interstate tunnel system once a month at selected time frames not expected to impact the majority of drivers, more extensive maintenance, construction, sign installation, electrical and other utility work can be accomplished.
MassHighway also wants to remind drivers they may experience delays this summer due to lane closures at night on I-93 North and South between Medford and Somerville and from Boston to Quincy from 9 pm to 5 am Sunday though Friday. These lane closures allow MassHighway contractors to complete pavement resurfacing, bridge deck and lighting repairs.
