RESCHEDULED

I-80 westbound lane closures Saturday as Bridge over Howard Boulevard project advances in Mount Arlington

Ramps between I-80 westbound and Howard Boulevard to be closed

(Trenton) – I-80 westbound is scheduled to have lane closures Saturday night to shift traffic as the Bridges over Howard Boulevard replacement project advances in Mount Arlington, Morris County. In addition, the ramp from I-80 westbound to Howard Boulevard and the Howard Boulevard ramp to I-80 westbound will be closed and detoured Saturday night at the same time. This work was originally scheduled for tonight, Friday, June 27, but was postponed due to weather.

I-80 westbound Lane Closures

Beginning at 8:30 p.m. Saturday, June 28, until 8 a.m. Sunday, June 29, I-80 westbound is scheduled to have lane closures beginning before the Bridge over Howard Boulevard until near mile post 32. Work will start with a single lane closure, before a second lane is closed. Additionally, construction is expected to begin in the left lane and move to the right as work progresses. At least one lane will be maintained overnight. The closure is necessary to install construction barrier and restripe the roadway to implement a traffic shift. If work is completed sooner, the lanes will reopen earlier.

By 8 a.m. Sunday, June 29, three lanes on I-80 westbound will be restored and shifted to the left onto the temporary roadway in the median. The traffic shift is necessary to demolish and reconstruct the I-80 westbound Bridge over Howard Boulevard and is expected to remain in place until fall 2026. 

I-80 westbound-Howard Boulevard Interchange Ramp Closures

Beginning at 8:30 p.m. Saturday, June 28, until 8 a.m. Sunday, June 29, the I-80 westbound Exit 30 ramp to Howard Boulevard and the Howard Boulevard ramp to I-80 westbound will be closed and detoured. The ramp closures are necessary to assist with the traffic shift and improve safety for the work zone on I-80. If work is completed sooner, the ramps will reopen earlier. The following detours will be in place Saturday night:

I-80 westbound Exit 30 ramp to Howard Boulevard Detour:

• Motorists on I-80 westbound wishing to take the Exit 30 ramp to Howard Boulevard/Mount Arlington will be directed to continue on I-80 westbound

• Take Exit 27A to Route 206 southbound/Somerville

• Go underneath I-80 and stay right to take the first ramp to I-80 eastbound/New York City

• Take Exit 30 to Howard Boulevard/Mount Arlington

Howard Boulevard ramp to I-80 westbound Detour: 

• Motorists on Howard Boulevard wishing to take the ramp to I-80 westbound will be directed to Route 46 westbound

• Stay right to continue on Route 46 westbound

• Stay right at the Crossroads Gas Station to I-80/Lake Hopatcong/Landing

• Stay left to take the ramp to I-80 westbound

The $65.4 million federally funded project will replace the existing bridges carrying I-80 eastbound and I-80 westbound over Howard Boulevard/CR 516, which are in poor condition. Improvements will include raising the vertical clearance of each bridge, widening the shoulders, lengthening acceleration and deceleration lanes on I-80, and widening the ramps to and from Howard Boulevard. The Howard Boulevard intersection will be reconfigured to improve operational performance.

The project will also include upgraded traffic signals and lighting, and ADA-compliant sidewalks and crosswalks. Sidewalks will be extended to the Mount Arlington Train Station for improved pedestrian and bicycle safety and mobility. The project is expected to be complete in summer 2027.

The precise timing of the work is subject to change due to weather or other factors.
