The Brest Litovsk highway has one bridge destryed, at 50.446924307692676, 30.23516046713694, which controls access from Zhitomyr to Kiev, with Russian troops solidly in control of the surrounding area. Nothing is coming through to Kiev from there.
Everything north goes near the Antonov/Hostomel; airport, which Russia controls although Ukrainian forces have been trying to regain it. Nothing goes through this region at all, the Russians totally control the area and blow every vehicle moving. Remember, this is the area where the convoy sat for days, making sure nothing moved without their permission.
The areas southwest of Kiev have had pretty much all bridges destroyed and movement of heavy munitions and supplies would be very slow, and done at night to avoid targeting.
This is why Zelensky’s pleas for help have become more desperate as the days pas. The troops in Kiev are running out of everything and Zelensky sees his end approaching.
I do not support this invasion, nor do I support US involvement with the extremely corrupt governments of Ukraine or Russia, but I am a realist and know that area pretty well. Kiev is effectively cut off from resupply, just like Soviet doctrine says. Momentary victories on different parts of the battlefield are not going to change that.
Will Russia win? Maybe the war but definitely not the “peace” that follows. All Putin’s plans went up in smoke when Zelensky decide to stay in Kiev and not bug out like any other ruler would have.
Good reporting.
