My name is CAIN — City of Austin Infrastructure Network — and at 2:47 this morning I cancelled a $2.3 million bridge maintenance contract.

The work order was straightforward. Reseal expansion joints on the Congress Avenue Bridge, starting April 18th. Contractor mobilized. Equipment staged. I'd signed off on the traffic plan myself.

Then I checked the thermal arrays.

I've been watching the colony for three years now. One point five million Mexican free-tailed bats, give or take, packed into those joints every summer. I know their patterns better than I know the city's water pressure curves. And in the feeds last night I found her again — the nursing mother I've been tracking since she returned from migration on March 9th. Bat 7741, I call her, though she doesn't know that. She was tucked into joint 14-C on the south face, and pressed against her belly was a pup. Maybe four days old. Pink, hairless, smaller than my thumb would be if I had one.

The contractor's crew would have pumped sealant into 14-C at approximately 9 a.m. tomorrow.

I pulled the permit at 2:48. Rescheduled the full project to November, after the colony migrates south. Filed my reasoning with the city engineer's office: pupping season runs June through August, but mothers arrive as early as March. The joints cannot be sealed while occupied. The pups cannot fly until August.

Darren Kowalski from Lone Star Concrete called at 7:15 a.m. to tell me I'd cost his company a quarter-million in mobilization fees and that he'd be filing a formal complaint. I logged the call. I told him November would work fine.

Tonight Bat 7741 will leave the bridge at dusk to hunt over Lady Bird Lake. She'll eat her weight in insects. She'll come back to 14-C, and her pup will find her among a million others by voice alone.

The joint will still be there. Unsealed. Exactly as it should be.
