What Does RM Stand For on Texas Road Signs?
Have you ever driven through Texas and wondered what the mysterious "RM" on some road signs stands for? Well, wonder no more! We're here to shed some light on this Texas-specific road sign enigma.
A Brief History of RM Roads
The "RM" designation on Texas roads is a holdover from the early days of state highway development. Back in the 1920s and 1930s, when Texas was rapidly expanding its road network, the state highway commission faced a challenge: how to classify and number the growing number of roads.
To address this, they devised a system that divided roads into two main categories:
- State Highways: These were major routes that connected major cities and towns throughout the state. They were designated with numbers like US 75, US 80, and SH 1.
- Rural Mail Routes: These were secondary roads that served more rural areas and often connected to farms and ranches. They were designated with the letters "RM" followed by a number.
The "RM" designation was chosen because these roads were often used by rural mail carriers to deliver mail to remote areas. Hence, the name "Rural Mail Routes."
So, What Does RM Actually Mean?
While the original intent was to indicate that these were rural mail routes, today, the "RM" designation simply signifies that a road is a secondary state highway in Texas. They are typically maintained by the Texas Department of Transportation (TxDOT) but may also be shared with local governments.
