RM 187 begins at its southern terminus with US Highway 57 (US 57), near Batesville,^[3][4] as a paved, two-lane, asphalt road. RM 187 winds through several miles of Southern Texas grassland. The highway passes several large ranches and farms along this course and intersects with several county routes and private roads. For this stretch of the route, RM 187 is heading in a northeast direction. The highway turns north about two miles (3 km) south of an intersection with FM 140.^[5] The two highways run concurrently for nearly one mile (1.6 km) before FM 140 turns westward.^[4] RM 187 continues north through rolling grasslands for almost 3.5 miles (5.6 km) before turning in a northeast direction. The route continues in this direction for about two miles before returning to a northerly direction. After about 15 miles (24 km), RM 187 intersects with US 90 and State Highway 127 (SH 127) in the small town of Sabinal.^[6] The highway continues through more hilly, rolling grasslands. A few miles later, the highway crosses the Sabinal River and proceeds past the Waresville cemetery, the Links of Utopia Golf Course, and the Utopia on the River Airport^[7] before passing through the "downtown" area^[8] of the village of Utopia.^[9][10]

RM 187 winds through nearly seven miles (11 km) of brushland, passing several large ranches and farms alongside the Sabinal River. The highway heads through the unincorporated community of Vanderpool^[7] and runs concurrently with RM 337 for a length of 1.1 miles (1.8 km). Separating and running northward,^[11] RM 187 continues along the southwestern edge of the Lost Maples State Natural Area.^[12] The highway turns northeasterly through a long stretch of brushland before reaching its northern terminus at SH 39.^[3][9][13]

RM 187 was designated as Farm to Market Road 187 (FM 187) in Uvalde County on June 11, 1945, from Sabinal to the Bandera County line. On June 25 of that year, it was extended from the Uvalde County line to Vanderpool; the designation changed from FM 187 to RM 187 upon crossing into Bandera County. The highway was extended from an intersection with US 90 to Garner Field on April 1, 1948, adding approximately 1.8 miles (2.9 km). On November 23, 1948, it was extended to a point 4.3 miles (6.9 km) south of Sabinal, while the previous extension was cancelled and redesignated FM 1023. The route was lengthened southward by 6.7 miles (10.8 km) to a dead end on July 15, 1949. The section in Uvalde County was redesignated RM 187 in 1954. RM 187 was again extended south on March 24, 1954, to an intersection with FM 140, adding approximately 6 miles (9.7 km). On May 2, 1962, RM 187 was extended 4.5 miles (7.2 km) northward, and it was extended to its present northern terminus at SH 39 on June 26, 1963, which added about 12.9 miles (20.8 km). On June 21, 1967, FM 2557 was redesignated as part of RM 187, adding approximately 13.5 miles (22 km) and extending it to its current southern terminus at US 57, although this did not take effect until construction on the 8.5-mile (13.7 km) segment from FM 140 to FM 2557 was completed.^[1]
