British Defence Intelligence Update Ukraine – 22 October 2022 - Kyiv Post

Russian forces continue to reinforce crossing points over the Dnipro River, and have completed a barge bridge alongside the damaged Antonovskiy bridge in Kherson.
Although the use of heavy barge bridges was almost certainly included in Soviet-era planning for operations in Europe, it is likely this is the first time the Russian military have needed to utilise this type of bridge for decades. Using civilian barges likely provides Russia additional material and logistics benefits, having lost significant quantities of military bridging equipment and engineering personnel during its invasion.
If the barge bridge sustains damage, it is almost certain Russia will seek to repair or replace damaged sections quickly, as their forces and crossing points over the Dnipro river come under increasing pressure in Kherson.
