| | Roadklahoma Terminus: Interstate 540 (Arkansas) |
 | | The 0 mile marker is the interstate's junction with I-40, which, regardless of if this portion is signed east-west, as it is, or north-south, as the newer section is, should be past the Mile 14 marker. |
 | | I-540 is shown going in one direction, but not in the other, strongly suggesting this exit marks the terminus point. |
 | | Most of the interesting-looking bridges actually ARE 540, so they have to be seen from other roads, mainly US-71, which runs a parallel course just east of 540. |
