State Highway OSR is a section of the Old San Antonio Road in east central Texasmarker. While most of the original Old San Antonio Road (that is, the section of the road that is not private property) follows State Highway 21, this state-maintained route provides a routing close to the original alignment of the road near and around the Bryan-College Station metropolitan areamarker.

Route description

From the east (i.e., traveling toward San Antonio), Highway OSR begins in Midwaymarker in Madison Countymarker, at its junction with Highway 21. It traverses northwest to an intersection with Interstate 45. It then travels southwest through the town of Normangeemarker in Leon Countymarker, and crosses U.S. Highway 190 and State Highway 6 north of Bryanmarker. After skirting Robertson Countymarker, the highway ends at another junction with Highway 21 in Brazos Countymarker, just east of the Brazos River.

"OSR" is the only state highway in Texas with a completely alphabetical designation and one of only two where the designation begins with a letter (Texas State Highway NASA Road 1 being the other with a beginning letter).
