# Ranch to Market Road 337

Ranch to Market Road 337 (RM 337) is a ranch-to-market road in Real and Bandera counties in Texas, United States, that connects Texas State Highway 55 (SH 55) in Camp Wood with Texas State Highway 16 (SH 16) in Medina. Passing through the canyonland of the Texas Hill Country northwest of San Antonio, the route is noted for its scenery. RM 337 was designated in 1945 between Camp Wood and Leakey in Real County. It was extended eastward several times in the 1950s and 1960s, reaching its present length in 1975.

## Route description

RM 337 begins at SH 55 in Camp Wood. The highway travels as a two-lane road along East 4th Street for a few blocks before leaving the city; leaving Camp Wood, the highway's route becomes rural and passes by many ranches and small subdivisions. RM 337 crosses Camp Wood Creek twice with the route traversing through hilly areas after the second crossing. The next several miles of the highway feature sharp curves as the roadway travels up and down steep hills. RM 337 straightens out near John Buchanan Road and travels through a more flat area then enters the Leakey city limits near an intersection with Patterson Creek Road.
In Leakey, the highway travels along 6th Street and intersects US 83, leaving the city limits near a crossing with the Frio River. East of Leakey, RM 337 continues to travel through hilly areas for several miles before meeting RM 187 near the Lost Maples State Natural Area. The two highways share an overlap for about a mile before RM 337 leaves the overlap at Vanderpool. RM 337 crosses the Sabinal River just east of RM 187 then travels through rural areas of Bandera County, passing by several ranches. The highway starts to parallel the West Prong Medina River at the Wheeler Road intersection and continues to run parallel to the river for about the next 12 miles (19 km). RM 337 crosses the North Prong Medina River then enters the community of Medina, ending at an intersection with SH 16.
RM 337 is known for its hairpin switchbacks and natural environment; it has been called one of the most scenic drives in Texas. Texas Monthly magazine named the road no. 18 on its list of "75 Things We Love About Texas" in its April 2006 issue.
