After crossing Chiltipin Creek, the route turns toward the northwest and has a partial interchange with US 77 Business before meeting the frontage roads of mainline US 77 (Future I-69E).

Past this intersection, SH 89 curves toward the west before reaching its northern terminus at an exit for southbound US 181 traffic; the expressway continues past this point as US 181 northbound toward Beeville.

[5] The construction of the roadway included ten bridges and two new drainage structures near the north end.

[11] The remaining section was transferred to US 80/SH 1 (did not take effect until this part of SH 89 was surfaced).
