FM 3078 status as a former U.S. highway during construction makes it built beyond the usual standards as a farm to market road. The two-lane road has broad lanes and paved shoulders. The road has bridges over all water crossings and no sharp turns or curves allowing a 70-mile per hour speed limit. The road travels through ranch land just north of the foothills of the Davis Mountains. There are no major intersections along the length of the road, and the road passes through no cities or towns before reaching its eastern terminus at Toyahvale. Along SH 17 about beyond the terminus at Toyahvale is a junction with Park Road 30 at Balmorhea State Park.
