Highway designations in Texas can often be confusing for travelers, with a range of acronyms and names that are unique to the state. From Farm-to-Market (FM) and Ranch-to-Market (RM) roads to business routes labeled as “BS”—short for Business State Highway—Texas features an extensive and diverse network of highways.
The FM and RM road system began in 1937, originally designed to help farmers access markets more easily. Over time, it has grown into a network of more than 3,400 routes. Of these, 3,257 are designated FM and 176 as RM. The distinction between farm and ranch roads is not always clear-cut.
“RMs are predominately in the Texas Hill Country and west; typically ranches instead of farms,” said Michael Chamberlain, director of data management in TxDOT’s Transportation Planning and Programming Division. “The roads themselves look about the same and are typically about the same size. So the only difference might just be cattle watching you on the side of the road instead of cotton.”
Texas also has a single Ranch Road: Ranch Road One, which leads to the LBJ Ranch. This is just one example among many uniquely named or numbered highways across the state.
Interstate highways play a significant role in travel throughout Texas, with 25 interstate routes covering more miles than any other state.
Texans also frequently use terms like “Loop” for major city bypasses or ring roads. In Houston, Interstate 610 is called “The Loop,” while San Antonio residents refer to Interstate 410 as “Loop 410.” However, not all official loops form actual circles; Austin’s Loop 1 (MoPac) runs through downtown rather than around it.
Business routes in Texas have their own distinctive signage conventions as well. A small letter below the route number can indicate which town’s business route comes first along a highway.

In related national transportation news, $19.6 million was recently awarded by the U.S. Department of Transportation’s Maritime Administration through its Small Shipyard Grant Program to support shipyard modernization efforts across multiple states ($19.6 million in grant awards). Additionally, new guidance from USDOT will distribute $7.3 billion to help states respond to extreme weather events as part of President Biden’s Bipartisan Infrastructure Law (New guidance). These measures reflect ongoing federal efforts to improve infrastructure resilience nationwide.
