UK Infrastructure and the North–South Divide

Why transport investment matters

Transport infrastructure connects homes, workplaces and markets. Roads and railways carry commuters and freight; ports handle ships and their cargo; airports serve passengers and air freight. As demand grows, congestion and overcrowding can make journeys slower and less reliable.

Improvements can increase capacity, meaning how much traffic a network can handle, and connectivity, meaning how well places are linked. These are different: a larger terminal may handle more passengers, while a new rail connection may make a previously difficult journey easier.

Reliable transport helps businesses receive supplies and deliver products. It also lets people reach a wider range of jobs and gives employers access to more workers. Construction creates employment, and spending by workers and businesses can support further jobs through the multiplier effect. However, developments cost money and can cause disruption, pollution or habitat loss.

Roads: reducing bottlenecks and improving access

In 2020, the government launched the second Road Investment Strategy, RIS2, with a planned £27.4 billion investment in England’s motorways and major A-roads. Its aims included increasing capacity, reducing bottlenecks and improving connections between regions.

One example is the A63 Castle Street improvement scheme in Hull, which is intended to improve access to the Port of Hull. Better road access helps freight move between the port and businesses inland. This shows why improving a port also requires attention to the roads and railways serving it: a larger terminal alone cannot prevent delays on surrounding routes.

Road schemes also illustrate the importance of safety. Smart motorways use technology to manage traffic, and some designs allow vehicles to use the hard shoulder as a traffic lane. In April 2023, planned new smart motorway schemes were cancelled following safety concerns. Increasing capacity must therefore be balanced against protecting road users.

Railways: moving more people between places

Rail investment can increase passenger capacity and provide an alternative to road travel. Different projects serve different geographical needs.

The Elizabeth line, which opened in London in 2022, provides an east–west connection serving places including Heathrow Airport, central London and Canary Wharf. It increases rail capacity, reduces some journey times and eases pressure on existing Underground services. Better access supports commuting and business activity.

The TransPennine Route Upgrade improves the railway between Manchester, Leeds and York. It includes electrification, improved signalling and station improvements. Electrification supplies electricity through overhead equipment to power trains. The project aims to provide faster, more frequent and more reliable services, improving access to jobs and education across northern England. Electric trains also avoid the local exhaust emissions of diesel trains, although their overall carbon impact depends partly on how electricity is generated.

HS2 is a high-speed railway being developed between London and Birmingham. Its original plans included extensions to Manchester and Leeds, but the northern extensions have been cancelled. The remaining project aims to improve rail capacity and reduce journey times between London and the Midlands. Its changing route, rising costs and environmental concerns show that the benefits and geographical reach of a development can change before it is completed.

Ports: handling larger ships and more freight

Port improvements include deeper-water berths, larger cranes, more storage and better connections to inland transport networks. These changes allow larger vessels to dock and cargo to be handled more efficiently.

Liverpool2, completed in 2016, is a £400 million deep-water container terminal. It allows the Port of Liverpool to accommodate some of the world’s largest container ships. This increases capacity and makes the port more competitive, particularly for trade with the Americas.

London Gateway, opened in 2013 at Thurrock in Essex, is a £1.5 billion development with facilities for large container vessels, automated handling and logistics. Efficient loading, unloading and onward distribution help reduce delays in moving goods. Together, these examples show that port capacity depends on both the ships a port can receive and how effectively it handles their cargo.

Airports: increasing capacity brings trade-offs

Airport capacity can be increased through runway changes or through terminal improvements that make passenger processing more efficient.

The proposed third runway at Heathrow would allow more flights, supporting tourism, business connections and employment. Government support was reaffirmed in January 2025, but support for a proposal is not the same as a completed runway. Expansion is controversial because additional flights would increase carbon emissions and noise, while construction could displace residents and damage habitats. More passengers could also increase congestion on surrounding roads.

The Manchester Airport Terminal 2 expansion, part of a development programme valued at over £1 billion, provides another approach. Additional terminal space, improved baggage handling and security facilities are designed to accommodate more passengers. Strengthening Manchester’s role as a gateway for northern England can support investment and employment outside London.

Understanding the north–south divide

The north–south divide describes broad regional differences in income, employment opportunities and living conditions. London and the South East generally have higher economic output and a greater concentration of highly paid jobs than many northern areas. Differences also appear in house prices, educational outcomes and life expectancy.

This is not a sharp boundary or a description of every community. Prosperous places exist in the North, and deprived communities exist in the South. Higher southern wages may also be accompanied by higher housing and living costs, so wages alone do not fully describe living standards.

The pattern partly reflects the changing economy. Northern cities such as Manchester, Liverpool and Newcastle developed around manufacturing, shipping and heavy industry. De-industrialisation removed many traditional jobs. Meanwhile, finance and other high-value services became concentrated in London and the South East. Uneven investment in transport, research and business development reinforced differences in opportunities between regions.

Strategies to reduce regional differences

Strategies try to attract investment, improve access to work and give regions more control over their development. They work through different mechanisms rather than simply transferring money from one region to another.

Transport investment can connect northern cities more effectively. The TransPennine Route Upgrade is a concrete example, while Northern Powerhouse Rail is a proposed improvement to links between major northern cities. Better connections can expand the area within which people can commute and help businesses reach customers and recruit staff. The Northern Powerhouse initiative also seeks to attract investment by promoting northern strengths, including digital and creative industries.

Devolution gives regional leaders greater control over areas such as transport, housing and skills. Greater Manchester is one example of an area with an elected mayor and devolved powers. From 2025, Greater Manchester and the West Midlands were among the first areas to receive integrated settlements: combined, multi-year budgets that allow transport, training and regeneration spending to be coordinated. The intention is to match investment more closely to local needs.

Investment incentives encourage businesses to locate and expand in selected areas. Investment Zones, including those in Greater Manchester and South Yorkshire, support sectors such as advanced manufacturing and digital technology through measures including tax relief, research support and skills investment. Freeports such as Teesside Freeport use tax incentives and simplified customs procedures to encourage manufacturing, logistics and trade.

Regeneration funding, including the UK Shared Prosperity Fund, supports local businesses, community infrastructure, employment and training. Improving skills alongside attracting employers matters: residents need suitable qualifications and access to transport to benefit from new jobs.

Why narrowing the divide takes time

These strategies aim to reduce regional differences; their existence does not prove that the divide has disappeared. Transport projects take time to build, and their benefits depend on businesses and residents being able to use them. HS2’s cancelled northern extensions demonstrate how changing plans can limit a strategy’s intended regional reach.

A stronger approach combines measures: transport connects workers to jobs, training develops the skills employers need, and investment incentives help attract businesses. Success should be judged through changes in employment, incomes and living conditions, rather than the amount spent alone.

Transport developments

• Roads: RIS2 launched in 2020 with planned investment of £27.4 billion. A63 Castle Street improvements aim to improve access to Hull’s port. Planned new smart motorways were cancelled in 2023 over safety concerns.
• Rail: Elizabeth line opened in 2022, increasing London’s capacity and east–west connectivity. TransPennine Route Upgrade includes electrification, signalling and station improvements between Manchester, Leeds and York. HS2 links London and Birmingham; northern extensions were cancelled.
• Ports: Liverpool2, completed in 2016, is a £400 million deep-water container terminal. London Gateway opened in 2013. Both accommodate large container ships and improve freight handling.
• Airports: Heathrow’s proposed third runway would increase flight capacity but brings noise, emissions and community impacts. Manchester’s Terminal 2 expansion increases passenger-handling capacity.

The north–south divide

London and the South East generally have higher economic output and more highly paid jobs than many northern areas. De-industrialisation in the North and service-sector concentration in the South contributed to uneven development. The pattern has local exceptions; higher wages can accompany higher living costs.

Strategies and mechanisms

• Transport upgrades: improve access to workers, jobs and markets.
• Devolution: regional leaders coordinate transport, housing and skills spending; example: Greater Manchester.
• Investment Zones and Freeports: incentives attract businesses and employment; examples: South Yorkshire and Teesside.
• Regeneration funding: supports businesses, training and community infrastructure.

Strategies work best together. Judge success by improved employment, incomes and living conditions—not spending or promises alone.
