I-80 Lane Closures Announced Across Morris, Passaic Counties: See Details

MORRIS & PASSAIC COUNTIES, NJ — Drivers on I-80 in Morris, Passaic, and Essex counties are scheduled to see overnight lane closures beginning Monday as a state transportation project gets underway.

According to the New Jersey Department of Transportation (DOT), the right lane on I-80 eastbound and westbound will be closed at five locations, one location each night, from 8 p.m. Monday until 6 a.m. Tuesday, and continuing at the same time each night through Friday.

The closures will take place between milepost 36.7 in Rockaway, Morris County, and milepost 54.8 in Totowa, Passaic County.

According to the department, the overnight lane closures are needed to place a construction barrier and set up long-term right shoulder closures for the start of an Intelligent Transportation Systems improvement project. At least three lanes will be maintained overnight.

By 6 a.m. each morning, the right lane is scheduled to reopen, but the right shoulder will remain closed for several months. The department reported that the shoulder closures are needed for overhead sign installation at four locations and an overhead sign upgrade at one location. Those long-term right shoulder closures are expected to remain in place through late summer 2026.

The work is part of a $6 million ITS project covering 18.2 miles of I-80. According to the department, the project runs from Rockaway to Totowa and includes overhead sign installation at four locations, an overhead sign upgrade at one location, and the installation of conduit and wrong-way detection systems at several ramps within the project limits.

The project is expected to be completed in spring 2027, according to the DOT. Portable variable message signs are being used to give drivers advance notice of traffic pattern changes tied to the work.

Motorists are advised to slow down, use caution, and expect delays when traveling through the work zone. The precise timing of the work may change because of weather or other factors, according to the DOT.
