Grade is usually expressed as a percentage - converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for flat, to 100% at 45 ...
Grade-separated road junctions are typically space-intensive, complicated, and costly, due to the need for large physical structures such as tunnels, ramps, and bridges. Their height can be obtrusive, and this, combined with the large traffic volumes that grade-separated roads attract, tend to make them unpopular to nearby landowners and residents.
After the city or county acquires right-of-way, TxDOT builds and maintains the road. [12] A number of these roads, generally west of US 281, [13] are designated Ranch to Market Roads, and one—Ranch Road 1—is simply a Ranch Road, serving the LBJ Ranch. Farm to Market Roads were first designated in 1941 and Ranch to Market Roads in 1942.
