Russian forces struck the Mayaki bridge on the M-15 highway on 9 August, the Institute for the Study of War reported. The strike severed a road link that ties southern Ukraine to Moldova and Romania. That Odesa–Reni route crosses the Dniester and feeds the Danube ports. Those ports have become Kyiv's main export outlet since Russian strikes crippled its Black Sea shipping.

Conflicting claims over the Mayaki bridge

Russian milbloggers reported the attack, though their accounts diverged sharply. One claimed that Russian forces had destroyed the span. Others published footage purporting to show that it still stands. A local outlet serving nearby Izmail reported on 9 August that the strike damaged the crossing. Ukraine's State Border Guard Service separately confirmed that authorities briefly restricted traffic on the route. Moscow had already targeted the same structure in December 2025.

Why the land corridor matters

Russia likely hit the Mayaki bridge to choke Ukrainian grain exports, ISW assessed. Those exports now move through a land corridor that Kyiv has leaned on since strikes disrupted its maritime routes. Moscow has steadily intensified this campaign since July 2026. Navy Spokesperson Captain Third Rank Dmytro Pletenchuk offered one measure on 31 July. He said Russian strikes had damaged more than 20 ships near the Black Sea and sharply slowed cargo flows. Meanwhile, the country's main farmers union weighed in on 15 July. The Ukrainian Agri Council estimated that Russian attacks had cut about a third of Ukraine's grain-export capacity.

Minister of Agrarian Policy and Food Taras Vysotskyi has described the fallout. He said the strikes are forcing Kyiv to reroute grain and cargo through the Danube River. Russia used the same playbook in July 2023. Back then, then-Minister Mykola Solskyi reported that strikes destroyed 60,000 tons of grain at Chornomorsk port overnight on 19 July. Therefore, ISW concluded, Russia is likely shifting its strikes from the sea corridor to the land corridor. The aim, analysts wrote, is to block grain exports and weaken Ukraine's wider economy.

Türkiye floats a Black Sea moratorium

Turkish Foreign Minister Hakan Fidan raised a separate track on 9 August. He said Ankara had proposed a Russian–Ukrainian moratorium on strikes against merchant ships in the Black Sea. Both Moscow and Kyiv have received the offer, Fidan added, and Türkiye now awaits their response.
