The former alignment remained unnumbered until the 1953 state highway renumbering, when it was designated as Route 157.

The route heads northward along North Shore Road, passing through the local commercial districts of Absecon.

Route 157 continues northward, intersecting with local roads in a small patch of forestry.

At an intersection with Faunce Landing Road, Route 157 turns to the northeast onto its final stretch.

Continuing through the forestry, the highway intersects with several local roads and traverses near some residential homes.
