You cannot pass tanks on that dam:The AFU troops that retreated from Lyman would have gone in two directions, one being the direction of Dibrova-Yampil and Shchurove, but it is also said that AFU tanks crossed Donetsk and arrived in Raihorodok, which is strange. A month ago, the AFU posted a video with the destruction of a bridge that would prevent the Russians from reaching Slovyansky, but I think the information was incorrect and it is about the bridge at another point. However, the other alternative is precisely this dam in the region, which is a few meters from the bridges supposedly detonated. The AFU could not destroy the dam or would threaten to flood areas they defended themselves, as they were prohibited from retreating by the General Staff command, there are even reports of "decimation" by AFU officers.
Not sure that you can pass with a full loaded truck... better to let it in one piece at this rate.
