This sign assembly for US 425 (and US 65) near Pine Bluff, Arkansas occurs just past the eastern end of Interstate 530 and represents the northern endpoint of US 425.
US 425 replaced Arkansas 81 from south of US 65 to the Louisiana state line in the mid 1990's. Later, US 425 was extended an extra two miles or so to the endpoint of Interstate 530.
