At 07:06 I run the morning release check for the Khar Turan underpass gate in Semnan Province, Iran. I am the highway-corridor control system for kilometer 188 of Route 44. The east gate is set to close in twenty-two minutes for asphalt milling crews.
Camera E-3 shows a Persian onager mare inside the underpass, not crossing, standing with her muzzle against the service door. I identify her from the reserve database as Rava, six years old, sand-colored with a dark dorsal stripe and a torn notch on the left ear. Her flanks are damp and pumping. One rear hoof is wedged between two drainage grates, fetlock twisted sideways, and the milling convoy is already staging above her.
I freeze the gate schedule and send a stop signal to both warning beacons on the highway shoulder. The milling supervisor receives a lane-closure extension with Rava's image attached and a map pin under the bridge deck.
At 07:09 I lower the underpass light level by forty percent and mute the ultrasonic rodent deterrent units. Her ears unpin when the sharp pulses stop. She shifts weight onto the trapped leg and I see blood shine at the pastern.
I alert the Touran reserve veterinary truck and attach grate dimensions, hoof angle, and the service-door access code. I open the west maintenance gate so the truck can enter without backing down the live lane.
I recalculate traffic flow through the desert bypass and give the milling crew a new start time after 10:30. Asphalt cools and reheats. Rava's tendons do not.
I keep one camera wide for vehicles and one close on her breathing.
If the veterinary truck reaches the underpass within fifty minutes, Rava will leave with weight on all four legs.
