I-80 Westbound Ramp and Truck Rest Area Closures in Mount Arlington

Detours and Upcoming Rest Area Repavement to Impact Local Traffic

MORRIS COUNTY, NJ – Major traffic adjustments are set for Mount Arlington as the New Jersey Department of Transportation (NJDOT) announced the closure of the I-80 westbound ramp from Howard Boulevard starting tonight. 

The closure, which begins at 8 p.m. on Friday, May 10, and is expected to last until Monday, May 20, is due to the ongoing bridge replacement project over Howard Boulevard. If work finishes ahead of schedule, the ramp will reopen earlier.

Motorists traveling on Howard Boulevard northbound who wish to access I-80 westbound will be rerouted via the I-80 eastbound ramp, then to Exit 34 on Route 15 toward Wharton/Dover/Sparta, merging onto North Main Street/CR 634, and continuing to Route 15 southbound to access I-80 westbound toward Delaware Water Gap. Those traveling southbound will be directed to continue on Howard Boulevard, turn onto Route 46 westbound, and follow signs to I-80 westbound at Lake Hopatcong Landing.

Additionally, the Truck Rest Area on I-80 westbound at mile post 32.3 will be closed for repaving starting at 8 p.m. on Friday, May 17, and will also remain closed for 10 days. NJDOT advises truckers and other motorists to plan alternate rest stops and routes.

The closures are part of a $65.4 million federally funded initiative to replace the aging bridges carrying I-80 over Howard Boulevard/CR 516. The project includes increasing bridge clearance, widening shoulders, extending acceleration and deceleration lanes on I-80, and widening the ramps at Howard Boulevard. Traffic signals and lighting will be upgraded, and ADA-compliant sidewalks and crosswalks will be added, extending to the Mount Arlington Train Station to enhance pedestrian and bicycle safety.

The project is slated for completion in summer 2027. NJDOT encourages motorists to stay informed of construction updates and real-time traffic conditions by visiting their traffic information website at
