Worth noting that the pontoon bridge was deployed on the Belarusian side of the Chernobyl exclusion zone, so it's still a bit up the road from the (former) town of Prypyat. It's interesting though that the Russians train river crossings in the Exclusion Zone proper, because they would need to cross it, if they strike from the North towards Kiev.
