Past I-287, I-80 gains local-express lanes with a 2-3-3-2 configuration. The road continues past more commercial areas, with the local lanes having an eastbound exit and westbound entrance at CR 637. After this, there is a large interchange with US 46 and the western terminus of I-280, at which point the local-express lanes end. From this point, I-80 continues east through wooded areas as a six-lane freeway, crossing into Montville. In Montville, there is a partial interchange providing access to Hook Mountain Road. After a turn to the northeast, the highway comes into Fairfield Township, Essex County, continuing through wooded surroundings as it heads north before turning east. Development near the road increases as it comes to the westbound exit and eastbound entrance with CR 613.
