Hammersmith Bridge in west London has been closed to motor traffic since April 2019 after engineers found fractures in its pedestals, leaving a five-mile stretch of the Thames without a vehicle crossing and disrupting daily life for thousands of residents and commuters.
The closure, now longer than Britain’s involvement in the Second World War, has outlasted multiple prime ministers and prompted a protracted dispute among Hammersmith & Fulham Council, Transport for London (TfL) and national government over responsibility, funding and repair options. Pedestrians and cyclists have been allowed to use the bridge since limited repairs, but the structure remains inaccessible to cars and buses.
Engineers identified tiny fractures and seized bearings in the bridge’s pedestals in April 2019, prompting an immediate closure to traffic. A heatwave in August 2020 exposed further cracks and led to additional restrictions, including a temporary halt to river traffic beneath the bridge. Emergency and long-term intervention plans have followed, but the bridge remains closed to vehicles.
Initial repair estimates put the cost at about £120 million; that estimate has since increased, with some council figures citing a potential bill of at least £250 million for major reconstruction, including proposals for a double-decker design carrying vehicles above and pedestrians below. Hammersmith & Fulham Council has said it cannot yet confirm whether the bridge’s river piers could support that design despite four years of testing. Transport Secretary Heidi Alexander has suggested the bridge may qualify for a new £1 billion national structures fund, but the Department for Transport has not confirmed eligibility.
The prolonged closure has shifted traffic onto alternative crossings, intensifying congestion on routes such as Putney High Street, which was named Britain’s most congested road in 2022. For residents of Barnes and nearby neighborhoods on the south bank, the loss of a direct vehicle crossing has lengthened journeys to hospitals, workplaces and shops. Barnes resident Heidi Patton said reaching hospital appointments has become “a major operation” for her disabled husband. Another resident, Louisa Barnett, said she was unable to cross in time to see her dying sister and is now preparing to relocate to the north bank to reconnect her business and home life.
Local campaigners and community groups are sharply divided over the bridge’s future. Some residents welcome the quieter streets and cleaner air generated by the lack of motor traffic. Tech designer Elaine Mannix said the area “felt cut off when the bridge first closed but now I love the peace.” Others, including members of the action group Hammersmith Bridge SOS, describe frustration with multi-year delays and bureaucratic wrangling. Group chairman Nigel Edwards has documented the history of missed maintenance and successive administrations’ failure to deliver a permanent solution.
Responsibility for the bridge’s upkeep has been a central point of contention. The structure is Grade II listed and sits on piers designed by Victorian engineer Sir Joseph Bazalgette, who supervised a 19th-century replacement. After the abolition of the Greater London Council in 1986, ownership of many bridges and crossings was split among different bodies; Hammersmith & Fulham Council was given responsibility for Hammersmith Bridge despite most users coming from the opposite borough, Richmond, and London-wide travel patterns.
Political blame has been levelled across parties and institutions. Local officials say the cost is beyond the capacity of a single borough to fund; Richmond Council, TfL and central government have each at times been criticised for not providing clear long-term funding. In September 2020, then-Transport Secretary Grant Shapps announced a Hammersmith Bridge Taskforce intended to co-ordinate repairs; the bridge reopened to pedestrians nearly a year after the worst of the 2020 damage, after £48 million was spent on new rubber bearings, decking and cycle lanes.
Since the restricted reopening, progress on a comprehensive repair plan has been slow. The taskforce has met infrequently, and officials have described ongoing consideration of a range of options. A local Member of Parliament warned recently that the current schedule could mean another decade before full vehicle access is restored.
Alternative proposals have surfaced from independent engineers who say a temporary, self-financing tolled bridge could be built to carry vehicles while the historic structure is repaired. Maritime engineers Beckett Rankine produced a 2019 plan that included options for a temporary crossing to the west or east of the existing structure; proponents say such a crossing could be erected quickly and fund its own removal after completion of repairs. Hammersmith & Fulham Council and TfL have dismissed or not fully endorsed the proposal, and critics say the plan was not properly examined before rejection. Beckett Rankine and independent engineers argue the scheme is technically feasible and cite recent quick restorations of other historic suspension bridges as precedents.
Engineering and conservation constraints complicate any intervention. The bridge’s Grade II listing requires sensitive treatment of historic fabric, and elements needing repair include pedestals, anchors and chain links. Authorities have said that any reconstruction must balance structural integrity, heritage considerations and the impact on river navigation and local streets.
The closure has also revived historical reminders of the bridge’s vulnerability. The structure has suffered previous attacks and threats, including attempted bombings linked to the IRA in the 20th century. Today’s debate focuses less on security and more on funding and governance: who pays, who decides, and how to reconcile local preferences with London-wide transport needs.
With the 200th anniversary of the original crossing approaching — work began on the first suspension bridge at Hammersmith in 1825 and it opened in 1827 — residents, engineers and politicians are still awaiting a durable solution that restores reliable river crossings for vehicles while preserving a listed Victorian landmark. For many who live and work on both sides of the Thames, the disruption has become a daily reality; for authorities, the bridge remains a complex and costly test of coordination between borough, city and national government.
