Just south of downtown, the highway crosses US 281 again, which is cosigned with both US 82 and US 287 (East Central Freeway).

Shortly after crossing the East Central Freeway, Loop 473 ends at Business US 287-J (Scott Avenue).

[3] Loop 473 was designated along an old alignment of US 281 on January 31, 1969, through the city when US 281 was relocated along the Henry S. Grace Freeway.

At first, the Loop 473 designation was a hidden, internal one as the route was publicly signed as Bus.
