Truckers and commuters crossing northern New Jersey on Interstate 80 face five days of lane closures in Mount Arlington, Morris County, where the left lane of I-80 is now closed in both directions so concrete can cure on the new bridge decks being built over Howard Boulevard, the New Jersey Department of Transportation (NJDOT) has announced.

The closures began at 9 a.m. on Wednesday, November 4 and are scheduled to remain in place until 9 a.m. on Monday, November 9. A single left lane is closed on I-80 eastbound and on I-80 westbound from mile post 29.8 to mile post 32.3 — a stretch of about two and a half miles through Mount Arlington. NJDOT says the long-term closures are necessary to cure the concrete that connects the newly constructed bridge decks over Howard Boulevard.

At least two lanes will be maintained in each direction while the work is under way, according to Morris County government, which relayed the same NJDOT announcement to local residents. NJDOT advises motorists to slow down, use caution and expect delays when travelling through the work zone. The precise timing of the work is subject to change due to weather or other factors, the department added.

A $65.4 million bridge replacement, not a routine repair

The closures are one stage of the Bridges over Howard Boulevard replacement project, a $65.4 million federally funded project that is replacing the existing bridges carrying I-80 eastbound and I-80 westbound over Howard Boulevard, also designated County Route 516. NJDOT says the existing bridges are in poor condition. The replacement will raise the vertical clearance of each bridge, widen the shoulders, lengthen the acceleration and deceleration lanes on I-80, and widen the ramps to and from Howard Boulevard.

The work goes beyond the interstate itself. The Howard Boulevard intersection will be reconfigured to improve how traffic moves through it, traffic signals and lighting will be upgraded, and ADA-compliant sidewalks and crosswalks will be built. Sidewalks will be extended to the Mount Arlington Train Station, which NJDOT says will improve pedestrian and bicycle safety and mobility for people reaching the station on foot. The full project is expected to be completed in summer 2027.

How this stage follows the October traffic shift

This week's closures follow an earlier stage of the same project last month. In a release dated October 22, NJDOT announced overnight lane closures on I-80 eastbound in Mount Arlington on the night of October 23-24 to perform a traffic shift and create a median work zone; by the morning of October 24, eastbound traffic had been shifted toward the right shoulder, a pattern the department said would remain in place through December 2026 so crews could work in the median. The November left-lane closures are the next step in that sequence: with traffic shifted, the new bridge decks have been built, and the concrete joining them now has to cure undisturbed.

Why this stretch of I-80 matters to truckers

Interstate 80 is one of the main east-west freight corridors in the United States, and its New Jersey section carries heavy truck traffic toward the New York metropolitan area and the region's ports and warehouses. Morris County sits on that route, and a lane loss in both directions for five straight days — spanning the rest of the working week and the weekend — is exactly the kind of slowdown that eats into delivery schedules. For Punjabi and other South Asian truckers who run I-80 into New Jersey and New York, and for the large Punjabi community in the Edison and Jersey City areas who use this corridor, the practical advice from NJDOT is simple: expect delays at Mount Arlington, build in extra time, and check conditions before rolling.

NJDOT directs motorists to its traffic information website, www.511nj.org, for construction updates and real-time travel information, and posts updates through its official channels. News 12 New Jersey and PIX11 also reported the closures to local audiences on November 4, underlining that this is a region-wide traffic event, not a minor overnight job.

What happens next

The left-lane closures are scheduled to lift at 9 a.m. on Monday, November 9, in time for the Monday morning commute — though NJDOT cautions that timing can change with weather or other factors. The wider bridge project, including the median work made possible by the October traffic shift, continues through December 2026 in its current traffic pattern, with full completion expected in summer 2027. Drivers and dispatchers should treat the Mount Arlington stretch of I-80 as a recurring work zone until then: check 511NJ before each run, and watch for further NJDOT stage announcements as the bridge replacement advances.
