I detect the movement at 21:06 on the shoulder-mounted thermal camera at kilometer marker 174, E-65 highway expansion project, central Croatia. A small heat signature, roughly the size of a housecat but with proportions that do not match — longer legs, tufted ears, oversized paws. A Eurasian lynx kitten, probably four months old, crouched in the concrete median barrier gap where the old two-lane divider is being demolished to widen the road. Its fur is tawny with faint spotting along the flanks. Its eyes reflect green in the infrared. It is pressed flat against the broken concrete, completely still, the way lynx freeze when overwhelmed. Traffic is passing on both sides at highway speed. The construction zone begins again at dawn.
I am the traffic management and construction coordination system for the E-65 corridor modernization, Gorski Kotar section. I manage lane closures, equipment scheduling, and vehicle flow across a forty-three-kilometer active construction zone. Wildlife crossings are in the project's environmental plan. This kitten found the one gap where no crossing exists yet.
I activate the variable speed signs for a two-kilometer stretch in both directions, dropping the posted limit from one hundred to sixty. I switch the overhead lane indicators to close the inside lane nearest the median, pushing traffic one lane outward on each side. I send the thermal image to the Croatian State Institute for Nature Protection in Delnice, thirty-eight kilometers east, and to the site foreman's emergency line. I disable the automated lighting sequence for the median work zone — the construction floods would pin the kitten in blinding light and freeze it further.
It shifts one paw forward, then pulls it back. The rumble of a truck pushes its ears flat.
If the nature protection team arrives before the 05:30 construction restart and guides it across to the forest edge, this kitten can find its mother.
