Texas State Highway 121
TX 121 starts from Interstate 35W in downtown Fort Worth. It heads northeast to I-820, then east with TX 183 for several miles. TX 183 continues east while TX 121 turns northeast going on the west side of DFW airport. Shortly after connecting with I-635, TX 121 takes frontage roads while 121 Toll takes the mainlanes.
