Ranch to Market Road 337 or RM 337 is a Texas state road that runs from Camp Wood east to Medina. The route was designated in 1945 between Camp Wood and Leakey in Real County, but was gradually extended eastward over the years until in 1968 it stretched to RM 187 at Vanderpool in Bandera County. In 1976, an additional 9.7 miles (15.6 km) were added east from RM 187 to connect to SH 16 in Medina, bringing the road to its present form.[2]
