In the U.S. state of Texas, U.S. Highway 87 is a U.S. Highway that begins near the Gulf Coast in Port Lavaca, Texas and heads north through San Antonio and Lubbock to the New Mexico border near Texline. US 87's southern terminus is at an intersection with State Highway 238 in Port Lavaca, Texas. It takes a northwesterly route out of the town, and follows this path all the way to Cuero, where it merges with (and is briefly co-signed with) US 183 before turning back toward the north. US 87 follows a gentle northwesterly route until just before Smiley, where it takes a more due-westerly turn.
