State Highway 89 (SH 89) is a state highway in San Patricio County in the U.S. state of Texas. The route serves as a bypass of Sinton to the northeast, connecting to U.S. Route 181 (US 181) at both ends.

Route description

The southern terminus of SH 89 is an at-grade intersection with US 181 and SH 188; northbound US 181 turns to the west, cosigned with westbound SH 188, toward downtown Sinton, and eastbound SH 188 continues toward Aransas County. 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.^[3][4]

SH 89 is a hurricane evacuation route.^[5]
