London's Millennium Bridge adopts age-old maritime tradition during repairs

London's iconic Millennium Bridge is currently undergoing crucial repair and cleaning work, leading to the revival of an ancient maritime practice. The bridge, initially opened in 2000, was temporarily closed for a three-week period to address essential maintenance issues, as reported by BBC. As part of this age-old tradition, a bundle of straw has been suspended from the bridge's central arch, aimed at alerting passing boats to the reduced headroom under the bridge. This practice is rooted in an ancient Port of London Thames bylaw and is being implemented for safety purposes.

The Port of London Thames Byelaws, specifically clause 36.2, outlines the requirement to suspend straw from a bridge's central arch when its headroom is diminished while remaining open to navigation. This peculiar maritime tradition, designed to ensure the safety of boats navigating the Thames, dates back to the bridge's opening year.

In a modern twist, workers clad in high-visibility jackets are responsible for lowering the straw bale using climbing ropes, making it a practical and effective way to warn river traffic of the altered conditions under the bridge. This unique approach is in line with the bylaw's intent.


The urgent repairs and cleaning work were deemed necessary due to the deterioration of a section of the bridge membrane, as reported by the City Bridge Foundation, a charity responsible for overseeing several of London's significant Thames crossings. These extensive repair efforts are ongoing around the clock to expedite completion, according to a report by The Guardian.

City Bridge Foundation's spokesperson commented on the tradition, stating, "This is one of those quirky traditions London is famous for, but it also does serve a practical purpose, to warn shipping when the headroom under a bridge span is reduced." The suspension of the straw bundle occurs when contractors are conducting work under the bridge, such as installing netting as part of the process to replace the separation layer between the aluminum bridge deck and the steel structure below.

The Millennium Bridge holds a special place in London's history as the first new pedestrian bridge constructed across the Thames in over a century. It serves as a vital link, connecting the City of London near St. Paul's Cathedral with the Tate Modern gallery at Bankside. Notably, it experienced wobbling issues on its opening day in June 2000, leading to a temporary closure until February 2002 when additional support struts were added.

Before the recent closure for repairs, the bridge also made headlines when an artist, known for painting miniature pictures on discarded chewing gum, appealed to have his creations saved as most of them were slated for removal during the maintenance works.
