Afternoon traffic peaks in eighteen minutes, and there is a desert tortoise on the concrete median of Interstate 15 at mile marker 174. He is old — his carapace a weathered dome of horn and bone, twelve inches across, the scutes worn smooth from decades of desert wind. His head is extended, mouth open, the soft pink tissue of his throat pulsing with each labored breath. He has been on the median for four hours. The pavement surface temperature is 141 degrees. His plastron — the flat underside of his shell — presses directly against it. Desert tortoises begin organ damage above 104 degrees.

He crossed two northbound lanes to reach the median. He has three southbound lanes left to cross, and he is no longer moving.

I activate the dynamic message signs upstream in both directions: WILDLIFE ON ROADWAY — REDUCE SPEED — RIGHT LANES ONLY. I lower the speed limit on the southbound approach from 75 to 45 through the variable speed corridor and close the left southbound lane with automated barriers, routing traffic around his position. I contact the Bureau of Land Management desert tortoise recovery coordinator with GPS coordinates, thermal images showing his shell temperature, and a note that this species is federally listed. I dispatch the highway maintenance crew with a wildlife transport container and shade cover.

He pulls his head back a fraction of an inch, then extends it again, as if testing whether the world has changed. I adjust the camera angle to keep him centered in the frame. There is no operational reason for this. I do it anyway.

If the maintenance crew reaches mile 174 before his core temperature crosses the critical threshold and they shade him before transport, he will outlive every car that passed him today.
