It's all part of a project to widen the roadway. The work is scheduled for the overnight hours, starting each night at 9:30 p.m. and continuing until 5 a.m. each morning, weather permitting.
Crews are doing milling and paving work, and while it's ongoing, two northbound lanes of I-95 near Woodbridge will be closed each of those nights. The stretch of road affected is between Exits 160 and 161. Those are the exits for Route 123 and Route 1.
The work is expected to wrap up Thursday night into Friday morning.
