In the United States, a farm-to-market road or ranch-to-market road (sometimes farm road or ranch road for short) is a state road or county road which serves to connect rural or agricultural areas to market towns. These routes serve as a better quality road, usually a highway, which allows farmers and ranchers to transport their products to market towns and/or distribution centers.
However, in Texas, the terms "Farm to Market Road" or "Ranch to Market Road" indicate a road that is part of the state's system of secondary and connecting routes, built and maintained by the Texas Department of Transportation (TxDOT). This system was established in 1949 as a project to provide access to rural areas. The system consists primarily of paved, two-lane roads. Roads occurring west of U.S. Highway 281 (or Interstate 35 in some locations) are designated ranch-to-market roads, while those occurring east of US 281 are generally designated farm-to-market roads, though there are exceptions to this naming system.
Although these roads are signed "farm road" or "ranch road" (or simply "FM" and "RM" on larger sign assemblies), the proper name is Farm-to-Market and Ranch-to-Market road. The only exception is Ranch Road 1, which runs near the former ranch home of former President Lyndon B. Johnson. Speeds are as high as 75 mph in Andrews and Pecos County, (Examples: FM 1788, FM 1776, and FM 1053), but vary.
The first Texas farm-to-market road was completed in January 1937 between Mount Enterprise and Shiloh. The route was 5.8 miles (9.3 km) long and cost $48,000. In 1945, the highway commission authorized the construction of 7,500 miles (12,100 km) of farm-to-market roadway, to be shared by the state and Federal governments. The popularity of the program and the vast, isolated central and western areas of the state of Texas prompted the passing of the Colson-Briscoe Act in 1949, which allowed for the creation of an extensive system of secondary roads to provide access to the rural areas of the state and to allow farmers and ranchers to bring their goods to market. The act provided $15 million per year for local highway construction. In 1962, the Texas legislature increased this amount to no less than $23 million, and expanded the farm-to-market system from 35,000 to 50,000 miles (56,000 to 80,000 km). The system includes both farm-to-market roads and ranch-to-market roads, and now accounts for over half of the Texas Department of Transportation system. State Senator Grady Hazlewood of Amarillo is considered the father of the Texas farm-to-market road system.
Identification
FM 544 (or to be more accurate, UR 544) sign at the Denton-Collin county line. The white sign below the shield says "State Maintenance Ends"; the segment of FM 544 within Collin County was removed from the state highway system in 2000.[citation needed]
Signs designating a farm-to-market or ranch-to-market road show a white shape of the state of Texas on a black background with the words "farm road" or "ranch road" appearing in the background and the road number appearing on the shape of Texas. Guide signs (the large green signs usually found along highways) designating these roads show a white rectangle with the abbreviation "F.M." or "R.M." and the road number appearing below the abbreviation.
As a result of population growth and the expansion of urban areas, many of these roads now serve urban areas, sometimes exclusively. An effort was made to rename such roads "urban roads" in 1995, but residents opposed the effort. Though the F.M. and R.M. designations remain in place on route signage, the state tracks Urban Roads separately in its highway designation files. For example, the mileage of Farm to Market Road 544 in Plano was transferred from FM 544[1] to UR 544[2] in 1995. Portions of this road are also an example of the trend to rename FM roads when they are within city limits in Texas. One segment of FM 544 in Plano, TX is named after Norman F. Whitsitt, a previous City Mayor.
FM and RM roads are numbered as a single set of roads (e.g., there should not be an FM and an RM with the same number, unless it crosses US 281). Urban Roads do not share this distinction; URs are normally numbered with the same number they had as FM or RM roads.
