NY 238 continues west into Attica, initially passing quietly through mostly residential areas of the village.

After three more blocks, the route descends into the Tonawanda Creek basin and meets with NY 98 at High Street.

CR 45 leaves NY 238 just outside Attica, and rejoins the state route about 2 miles (3.2 km) later in Darien.

After CR 45's western terminus, NY 238 turns more northward again, entering a residential area and terminating at a junction with US 20 in the hamlet of Darien.

[3] NY 238 was assigned as part of the 1930 renumbering of state highways in New York to the portion of its modern alignment between Orangeville and Attica.
