Giant Steel Pipe Emerges in Osaka, Causing Traffic Disruptions

On March 11, 2021, a giant steel pipe unexpectedly protruded from a construction site in the bustling Umeda area of Osaka, Japan, rising as high as 13 meters (42 feet) above ground. The 27-meter-long (approximately 89 feet) pipe, with a diameter of 3.5 meters (11.5 feet), was discovered by a passerby who reported it to local authorities early in the morning. The incident led to immediate road closures near the elevated Shin-Midosuji highway, causing significant traffic congestion.

The pipe was part of an underground construction project aimed at connecting an existing sewer line to a channel designed for rainwater storage, intended to mitigate flooding risks. According to officials, the pipe's elevation was likely caused by the draining of water from its interior, which allowed it to float due to buoyancy. Following the incident, firefighters intervened by injecting water back into the pipe, which helped to lower it back down to a more manageable height. As of March 12, approximately 1.6 meters (5.2 feet) of the pipe remained above ground, prompting city officials to plan its removal.

They stated, "We are currently proceeding with work at the site cautiously while conducting safety checks," emphasizing the need for ongoing traffic restrictions in the area. The city's construction bureau is set to cut off the remaining visible portion of the pipe, which will necessitate further road closures for several days.
