2025年4月30日午前3時半ごろ、京都市下京区高倉五条交差点付近の国道1号で冠水が発生し、大量の水が周辺の道路にあふれた。
この影響で、五条通は、富小路通ー東洞院通の西行きを全面通行規制し、東行き4車線のうち2車線を東行き、1車線を西行きとして対面通行をしている。高倉通が五条通ー下坂通で通行止めになっている。

At around 3:30 a.m. on April 30, 2025, flooding occurred on National Route 1 near the Takakura-Gojo intersection in Shimogyo Ward, Kyoto City, causing a large amount of water to overflow onto the surrounding roads.
As a result, Gojo-dori was completely closed to traffic westbound from Tominokoji-dori to Higashinotoin-dori, with two of the four eastbound lanes being used for eastbound traffic and one lane being used for westbound traffic, allowing two-way traffic. Takakura-dori was closed from Gojo-dori to Shimosaka-dori.
