Route 184's western end is at an intersection with the Garden State Parkway in Woodbridge Township; its eastern end is at an intersection with Route 35 in Perth Amboy.

The route, immediately concurrent with CR 501 is known as King Georges Road, which turns to the north near Fords Park.

Just after the split from King Georges Road, Route 184 enters a partial cloverleaf interchange with US 9 and passes south of Hopelawn Park.

After passing the local cemetery, the route crosses a junction with CR 655 (Florida Grove Road).

The highway was an alignment from the new Outerbridge Crossing to Route 4.
