## Prediction

Within seven days, Ukrainian hits on the Mariupol–Donetsk highway bridge and Arabat Spit crossings are likely to measurably slow Russian logistics into southern Donetsk and Crimea, forcing longer, more vulnerable reroutes. Russian forces will attempt rapid bridging and construction of alternate crossings, but heavy equipment and ammunition flows will be temporarily constrained. This could reduce the intensity of Russian offensive operations on selected sectors while increasing Russian reliance on rail and maritime links that are more targetable. Confirmation would be reported Russian logistical delays, supply shortages at frontlines, or visible congestion on alternative routes; denial would be evidence of seamless resupply via newly completed crossings and unaffected operational tempo.

## Drivers

- Reports of Ukrainian strikes destroying a key Mariupol–Donetsk bridge and cutting the road
- Confirmed strike on Kherson–Crimea Arabat Spit bridge and subsequent construction of new crossings
- Emerging pattern of Ukrainian focus on deep logistics and crossings
