Hammersmith Bridge has been closed to motor traffic since April 10, 2019, after engineers discovered fractures in the masonry pedestals that support the suspension chains, leaving a key Thames crossing unusable for vehicles for more than six years.
Officials and local campaigners say the closure has created persistent transport disruption across west London, forcing thousands of extra vehicles onto alternative routes, delaying some emergency journeys and prompting sharp criticism of local and national authorities for a failure to find a long-term solution.
The Grade II-listed Victorian suspension bridge, first opened in 1827 and rebuilt in its current form by Sir Joseph Bazalgette in the 19th century, was immediately closed to vehicles when tiny fractures were spotted in the pedestals. Pedestrians and cyclists were later allowed to cross after emergency works, but motor traffic remains banned.
Initial repair estimates in 2019 put the cost at about £120 million. That figure has since risen, with Hammersmith and Fulham Council saying a preferred option — a double-decker design carrying vehicles on an upper deck and pedestrians below — could cost upward of £250 million. The council also says four years of testing have not yet confirmed whether the river piers could safely bear the weight of that design.
Transport Secretary Heidi Alexander has indicated the bridge might qualify for a new £1 billion Structures Fund for ageing infrastructure, but the Department for Transport has not confirmed eligibility or offered guaranteed funding. Local authorities, Transport for London and Whitehall officials have repeatedly pointed to each other as responsible for taking the lead on long-term plans.
The closure has concentrated traffic on nearby Putney Bridge and adjoining routes. A Transport for London congestion survey in 2022 named Putney High Street among the capital’s most congested roads. Local residents and community groups say journeys that previously took minutes by car now take an hour, complicating medical appointments and daily life for some.
"Getting to any hospital appointment is a major operation," said Barnes resident Heidi Patton, whose husband is disabled and requires regular treatment. Another south-bank resident, Louisa Barnett, said the closure cost her the chance to reach a dying sister in 2023. A member of the Hammersmith Bridge SOS campaign, writer Julia Watkins, said many locals feel their "lives feel smaller because they can’t move around like they used to."
Not all locals want the bridge reopened to traffic. Some Barnes residents have welcomed the reduced noise and improved air quality since 2019. "We love all the clean air. Keep it like this," said one dog-walker, reflecting a view voiced in parts of the affected community.
Responsibility for the bridge has been a point of contention for decades. After the abolition of the Greater London Council in 1986, responsibility for various crossings was split among bodies including Network Rail, Transport for London and individual borough councils. Hammersmith Bridge came under the ownership of Hammersmith and Fulham Council, a mismatch critics say failed to account for the high proportion of users from neighbouring Richmond upon Thames.
The structure’s condition was further aggravated by historical damage inflicted during IRA attacks in 1939, 1996 and 2000, but local campaigners and engineers attribute the current crisis primarily to years of deferred maintenance. In August 2020, a summer heatwave exposed fresh cracks and prompted an escalation in emergency measures, including a temporary closure to boats below the structure. International media coverage heightened political pressure and led to the creation of a government "Hammersmith Bridge Taskforce."
Work since then has included the installation of new rubber bearings and replacement decking, at a reported cost of about £48 million, and the creation of cycle lanes to enable riders to cross without dismounting. Access for pedestrians and cyclists resumed in limited form, but the bridge remains structurally unfit to bear the loads of motor vehicles.
A number of engineering solutions have been proposed. One widely publicised suggestion from maritime engineers Beckett Rankine in 2019 included two temporary, self-funding toll-bridge options to run parallel to the existing crossing while the Victorian span was dismantled and rebuilt in sections. Proponents say a temporary modular bridge could be erected within months and fund itself through tolls, allowing comprehensive repairs to proceed at lower cost and greater speed.
Tim Beckett, representing Beckett Rankine, said temporary standard units could be in place within three to four months with appropriate planning consent and that the old bridge could be repaired over about five years before the temporary structure was removed. He pointed to the recent restoration of the Union Chain Bridge between England and Scotland, a similar suspension structure refurbished in two years at a cost he said was a fraction of current estimates for Hammersmith.
Council officers and Transport for London have previously rejected the Beckett Rankine proposal, with the council saying TfL engineers made the decision. TfL said it continues to work with the government and the borough and that ultimate responsibility for the crossing rests with the local authority. Council members and some local opposition politicians contest that the proposal has not been fully examined, particularly the western alignment option that could start on land owned by St Paul’s School.
Local engineers and members of campaign groups say the planning and political process has been slow. "We are a major G7 nation and I cannot think of any other country which would allow a vital piece of infrastructure in the heart of the capital simply to fall apart," said Nigel Edwards, chairman of the action group who has documented years of inaction.
Hammersmith Bridge is listed by Historic England as Grade II, a designation signifying its national importance and requiring consent for substantial alteration. Elements identified as needing repair include the stone pedestals, anchors and the suspension chains. Any plan to close the structure to undertake repairs or dismantle sections will require careful heritage oversight and planning permission, adding complexity and time to projects.
The council has warned that the preferred double-decker option would be expensive and that testing has not yet resolved key load-bearing questions. Planning permission granted in recent months for more than 1,000 homes at Mortlake, south of the bridge, raises further worries among residents and local politicians that demand for crossings will grow if no vehicle solution is found.
Calls for a decisive plan have been made across the political spectrum. Some local councillors and residents advocate for a temporary toll bridge to the west as a pragmatic interim measure. Opponents say such a proposal would affect parking, trees and local amenity and face electoral resistance in neighbourhoods through which a temporary approach would pass.
Since the formation of the taskforce, its meetings have been infrequent; campaigners note only one meeting of the group since the most recent national election, with officials reportedly commissioning further traffic surveys as part of ongoing assessments. Transport and borough officials say they are "considering a range of options," while the Department for Transport has yet to commit long-term funding.
As the bridge approaches its bicentenary of the original 1825 start of construction — a milestone some campaigners hoped might spur action — residents, engineers and politicians remain at odds over who should pay, what engineering method is practicable and how long full restoration will take. A local MP has warned the present schedule could stretch for another decade, a prospect that keeps the crossing closed to motor vehicles and maintains a daily re-routing of traffic across west London.
The Hammersmith Bridge case highlights the technical, financial and political challenges of repairing historic infrastructure in a densely populated capital. With competing proposals on the table and limited clarity over central funding, the crossing’s future remains uncertain and continued disruption is likely until a funded and engineered plan is agreed and implemented.
