The route then turns slightly to a more northerly course as it gains a median strip between its four lanes, just before reaching its next intersection with East 2nd Street.

Next the route quickly reaches a diamond interchange with Interstate 80 (Exit 178), followed by a T intersection with the south end of See Drive (a dirt road which very briefly heads southeast from SR 289 before turning northwest and then looping back to SR 289).

After passing See Drive, SR 289 loses its median strip and narrows to a two-lane road; remaining as such for the rest of its length.

Traveling through rural area, the route passes northwest of a mobile home park before leaving the city limits of Winnemucca[Note 1] and immediately reaching a T intersection with the north end of See Drive (which heads southeast from the route and is paved for a short section on its north end).

[Note 2] From the eastern terminus of SR 289, East 2nd Street continues northeast through Weso to end near the south bank of the Humboldt River.
