TAIPEI (Taiwan News) — The Transportation Highway Bureau said Tuesday it will identify the source of a persistent whistling noise at Danjiang Bridge and propose solutions before the end of March.

Residents living near the Bali end of the bridge in Bali District have reported hearing a high-pitched sound similar to a boiling kettle when northeasterly winds blow across the structure, per CNA.

DPP New Taipei City councilor Cheng Yu-en (鄭宇恩) confirmed the phenomenon after visiting the area, per Liberty Times. Cheng said that while the noise is not as loud as sounds from construction sites, prolonged exposure could still disrupt residents’ daily lives.

Highway Bureau official Cheng Min-chung (鄭閔中) said the bridge’s design team inspected the site on Jan. 27. Preliminary assessments suggest the noise may result from interactions between the pedestrian handrails and northeasterly winds.

Cheng Min-chung said the bureau will determine the cause and present possible remedies before the end of March. Industry experts suspected that the phenomenon may be an aeroacoustic effect caused by wind interacting with the bridge’s cables, per ETtoday.

Responding to the concerns, New Taipei Mayor Hou Yu-ih (侯友宜) said the city government has held meetings with the Highway Bureau and also concluded the noise likely stems from aeroacoustic effects, per FTNN. He added that authorities are already working to identify potential solutions.
