US road-repair warning offers a cautious test for London transport spending

A new US transport-spending analysis has warned that road agencies are moving too slowly from expansion to repair, offering a useful but limited comparison point for London debates over how transport authorities and boroughs prioritise maintenance, renewals and new schemes.

Transportation for America, a US advocacy and research organisation, published its latest Repair Priorities findings on 22 July 2026. The report, as summarised by the organisation, says US states have increased the share of transport funding going into road repair, but not fast enough to produce major improvements in road condition after years of expansion-led spending.

The figures are American and should not be read as evidence about the condition of London roads. The relevance for London Urbanism Desk readers is narrower: the report sets out a policy test that can be applied locally whenever transport budgets, road renewals, public-realm schemes and new capacity proposals are assessed. Are agencies protecting existing assets first, or are future maintenance costs being pushed beyond the visible project budget?

What the US report says

Transportation for America says its Repair Priorities 2026 analysis found that, across US states, an average of 39 per cent of transport funding went to road repair and 25 per cent to expansion in the 2018 to 2024 period. Despite that shift, the organisation says the share of federal-aid-eligible roads rated in poor condition fell by only three percentage points nationally.

The report’s central argument is that a late move towards repair can fail to catch up with years of under-maintenance, especially when construction and labour costs have risen and agencies continue to fund new infrastructure that will also need to be maintained.

The organisation uses West Virginia and Michigan as examples of different versions of the same problem. In West Virginia, it says a major expansion programme left the state with long-term debt obligations and limited room to address future upkeep. In Michigan, it says relatively high maintenance spending has not delivered strong outcomes because too much money has been absorbed by costly reconstruction rather than earlier preventative work.

Key facts

Why this matters to London readers

London’s transport governance is different from the US state highway systems discussed in the report. Transport for London, boroughs, central government and private developers all play different roles in streets, junctions, bridges, buses, cycle routes, utilities coordination and public-realm works. That means the US findings cannot be mapped directly onto London budgets or road conditions.

The policy question, however, is familiar. London routinely has to balance maintenance and renewal of existing streets and transport assets against calls for new schemes, corridor upgrades, development-related works and public-realm improvements. Some projects are justified because they improve safety, accessibility, bus reliability, walking conditions, cycling access or climate resilience. Others can create future obligations that are less visible when the scheme is announced.

The useful test from the Transportation for America report is whether public bodies are showing the whole cost of a transport decision: not just design and construction, but inspection, resurfacing, drainage, structures, signals, utilities disruption, enforcement, cleaning, planting, lighting and eventual replacement.

Repair before expansion is not always simple

A repair-first argument can sound straightforward, but London streets are not only carriageways. A resurfacing programme may interact with bus priority, pedestrian crossings, cycle tracks, kerbside loading, drainage, tree pits, traffic signals, utilities and accessibility works. In dense urban corridors, delaying a redesign until after like-for-like repair can sometimes lock in poor layouts for years.

That is why the lesson is not simply “spend less on new things”. It is to distinguish between expansion that adds long-term liabilities without solving an urgent urban problem, and renewal that uses maintenance moments to improve safety, access and resilience. A street can be repaired badly, repaired adequately, or repaired in a way that reduces future risk and supports more reliable movement.

The US report’s emphasis on preventative maintenance is particularly relevant to this distinction. Transportation for America argues that waiting until roads fall into poor condition leads to more expensive reconstruction and larger backlogs. For London, the equivalent scrutiny would ask whether asset-management decisions are being made early enough, and whether borough and TfL programmes are coordinated so that the same streets are not repeatedly disrupted by separate works.

What to check in London budgets and papers

For London readers following transport and public-realm decisions, the report suggests several practical checks when new projects, budget papers or committee reports appear.

First, look for a clear split between maintenance, renewal, enhancement and expansion. If a scheme is described as an improvement, the documents should explain whether it renews existing assets, adds new assets, or does both.

Second, look for whole-life cost assumptions. A new junction layout, bridge intervention, cycle route, bus-priority corridor or public square may have a capital cost, but it should also have a credible maintenance plan.

Third, check whether preventative work is being prioritised before more expensive reconstruction becomes unavoidable. The Transportation for America analysis argues that agencies can spend more on repair and still get poor outcomes if they intervene too late.

Fourth, ask who will own and maintain the asset after delivery. In London, developer-funded public realm, borough highways, TfL roads, transport interchanges and estate roads can involve different long-term responsibilities. A project that looks funded at delivery stage may still leave unresolved questions about upkeep.

The limits of the comparison

This is not a claim that London faces the same financial or physical conditions as West Virginia, Michigan or any other US state cited by Transportation for America. The source material does not assess TfL, London boroughs, UK highway maintenance funding or the condition of London’s road network.

It is also not evidence that expansion is always the wrong priority. In a growing city, new transport capacity, safer crossings, bus-priority measures, accessible interchanges and climate-adaptation works may be necessary. The issue raised by the US report is whether agencies can demonstrate that they can afford to maintain what they already have while taking on new commitments.

For London, the strongest follow-up evidence would come from TfL budget and business-plan documents, borough highway asset-management strategies, London Assembly scrutiny papers, Department for Transport funding material and local committee reports. Those sources would be needed before making firm claims about maintenance backlogs, road condition trends or the balance between renewal and expansion in the capital.
