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 completed in summer 2027.

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